Collective model: (1959YU1A, 1960RA1A, 1960SH1A, 1961NE1B, 1962AR1C, 1962DA1B, 1962MA1K, 1962MA23, 1962MA32, 1962MO1B, 1963CH02, 1964BA1L, 1964BR1H, 1965NE1C, 1966BR04, 1966BR1R, 1966BR1Q, 1967FE01, 1967GO04, 1967GR1D, 1968BI07, 1968EL1C, 1968MA2B, 1969BA2E, 1969MA38, 1970BA2B). Electromagnetic transitions: (1959BA1C, 1959FA1C, 1960RA1A, 1962MA1K, 1962MA32, 1963CH02, 1964BA1L, 1965GR1H, 1965KA1D, 1966MA12, 1966QU1A, 1967KA21, 1969KH1C, 1969MA38, 1970EL08, 1970GO1H, 1970SI1C). Special levels: (1961WI1D, 1962IN02, 1963CO12, 1965EJ1A, 1965GI1B, 1965LE1E, 1965NE1C, 1966SO05, 1967BE02, 1967GR1D, 1967PF01, 1967PI01, 1968MA2B, 1969BA2E, 1969GI1B, 1969HA1G, 1970BA2B, 1970EL08, 1970RY02, 1970WA01). Other topics: (1959FE1B, 1959KH1A, 1959SA11, 1960GO1C, 1963WA1E, 1964LI1B, 1964NI1A, 1965HU1D, 1965ZA1B, 1966MI1F, 1966WA1K, 1967EL03, 1967GR1H, 1967KA1G, 1967LY02, 1967NI1D, 1968KA1E, 1968NI1A, 1968SU1F, 1968SU1C, 1968SU1E, 1968WO1C, 1969DE16, 1969FO1G, 1969HE1N, 1969IW1B, 1969JA1P, 1969KA09, 1969NO03, 1969NO1E, 1969PA1G, 1969PI1D, 1969SA1J, 1969SC14, 1969SC1Q, 1970BA1M, 1970HA1T, 1970MC17, 1970SU1B). Ground state: Q = 26.5 ± 3.0 mb (1964LI14). See also (1959FA1C, 1960RA1A, 1962BE1D, 1963BE36, 1964ST1B, 1965IC1A, 1966MA1V, 1966MA19, 1966MI1F, 1967CO1D, 1967GO1A, 1967GR1D, 1967SH05, 1968BE1X, 1968LE1L, 1968PE16, 1968RO1E, 1969CH1R, 1969FU11, 1969SI1E, 1970EL08, 1970SI02, 1970SI1C).
The angular distribution of the αparticles corresponding to ^{17}O*(0, 0.87) (unresolved) has been measured at E(^{14}N) = 27.6 MeV (1964WA1B).
The lifetime of ^{17}O*(0.87), τ_{m}, is 253 ± 6 psec (1969NI09): see Table 17.7 (in PDF or PS). At E(^{16}O) = 15 and 18 MeV, the transitions to ^{17}O*(0, 0.87) have been studied (1970BA1J). The excitation curve for the oneneutron transfer to ^{17}O*(0.87) has been measured for E(^{16}O) = 6 to 22 MeV (1970BA55). See also (1968KN1A).
Cross sections to various of the final states have been measured at E(^{7}Li) = 5.20 MeV (1966MC05). See also (1963MO1B).
Cross sections to various of the final states have been measured at E(^{6}Li) = 4.72 MeV (1966MC05). See also (1963MO1B).
Angular distributions have been reported at E(^{6}Li) = 3 MeV (1963BA08; p_{2}, p_{3}, p_{4}), 3.4 to 4.0 MeV (1962BL13; p_{0} → p_{3}), 4.5 to 5.5 MeV (1966HE05; p_{0} → p_{4}), 5.6 to 6.6 MeV (1970JO09; p_{0} → p_{3}), 9.0 to 14.0 MeV (1970JO09; p_{0} → p_{4}) and 20 MeV (1968ME10; p to ^{17}O*(8.47)). Neither the direct reaction model nor the statistical compound nucleus model alone is adequate to describe the data (1970JO09). Proton groups to various states of ^{17}O with E_{x} ≤ 15.8 MeV have been identified by (1966HE05, 1968ME10, 1970JO09). See also (1960SH05, 1967DZ01), (1967CA1D), (1968GA1J, 1969GI1B; theor.) and ^{18}F in (1972AJ02).
Angular distributions of the d_{0} and d_{1} groups have been measured at E(^{7}Li) = 3.24 to 3.64 MeV (1967MO23). At E(^{7}Li) = 20 and 24.4 MeV, deuteron groups are observed to many states of ^{17}O with E_{x} < 15 MeV, including states at E_{x} = 8.50 and 11.85 MeV and probable T = 3/2 states at 11.08, 12.47, 12.99, 13.64, 14.28 and 14.80 MeV (1969BA2U, 1970COZA). See also (1970CA1N) and ^{19}F in (1972AJ02).
The yield of neutrons (reaction (a)) increases monotonically for E_{α} = 0.475 to 0.700 MeV: S(E) = [(5.48 ± 1.77) + (12.05 ± 3.91)E] × 10^{5} MeV · b (1968DA05). The astrophysical considerations are discussed by (1968DA1D). See also (1959AJ76). Elastic scattering studies (reaction (b)) have been carried out for E_{α} = 2.0 to 3.5 MeV (1965BA32) and 3.5 to 6.5 MeV (1968KE02). Recent measurements of yield curves for reaction (a) have been made at E_{α} = 2.0 to 3.5 MeV (1965BA32), 2.0 to 5.6 MeV (1967SE07; σ_{t}), 3.5 to 6.5 MeV (1968KE02), 4.5 to 10.5 MeV (1970RO08; n_{0}), 5 to 10 MeV (1963SP02: 6.13 and 7 MeV γ) and 17.4 to 22.5 MeV (1963DE27; n_{0}). Angular distributions have been measured at many energies. A number of resonances in the neutron yield and of anomalies in the elastic scattering have been observed: see Table 17.6 (in PDF or PS) (1953JO1A, 1956BE98, 1956BO61, 1956RU1A, 1957WA46, 1963SP02, 1965BA32, 1967SE07, 1968KE02, 1970RO08). See also (1960ST02). Table 17.6 (in PDF or PS) also shows the results from the inverse reaction ^{16}O(n, α)^{13}C. The study of the n_{0} yield by (1970RO08) indicates more structure than is displayed in Table 17.6 (in PDF or PS). In the range E_{n} = 17.4 to 22.4 MeV the n_{0} cross section does not show any appreciable variation with energy. See also (1968LE1N) and (1963KE1A; theor.). J^{π} assignments derived from polarization measurements at E_{α} = 3.36 to 4.80 MeV are displayed in Table 17.6 (in PDF or PS) (1971BA06). See also (1969SC04).
At E(^{6}Li) = 18 MeV, deuteron groups have been seen corresponding to many ^{17}O states with E_{x} < 9 MeV: see Table 17.8 (in PDF or PS) (1970BE31). See also (1968OG1A, 1970OG1A).
This reaction has been studied at E(^{7}Li) = 17 MeV: see reaction 8 and Table 17.8 (in PDF or PS) (1970BE31). See also (1968OG1A).
At E(^{16}O) = 17 and 20 MeV, the transitions to ^{17}O*(0, 0.87) have been studied (1968KN1A, 1970BA1J). The excitation curve for the oneneutron transfer to ^{17}O*(0.87) has been measured for E(^{16}O) = 12 to 25 MeV (1970BA55).
The n_{0} yield (reaction (a)) for E(^{3}He) = 1.6 to 3.25 MeV indicates two resonances at E(^{3}He) = 2.1 and 2.8 MeV, corresponding to ^{17}O*(20.5, 21.1) (1961JO24). The excitation function shows a resonance in the n_{0} and n_{3+4} yields at E(^{3}He) = 4.1 MeV [^{17}O*(22.1)], but not in the n_{1+2} yield: J^{π} = 1/2^{} or 3/2^{} is suggested (1970HO08). Resonances are observed in the αyield (reaction (c)) at E(^{3}He) = 3.6 and 4.1 MeV [^{17}O*(21.7, 22.1)] and in the ^{3}He yield (reaction (b)) at 5.1 MeV [^{17}O*(23.0)], with J^{π} = (5/2^{+}), (7/2^{}) and (1/2^{+}), respectively (1970KE1D). The variation of the ^{3}He optical parameters has been studied for E(^{3}He) = 10 to 18 MeV (1970DU07).
A study of n  γ correlations leads to J^{π} = 1/2^{} for ^{17}O*(3.06) and probably to J^{π} = 5/2^{} for ^{17}O*(3.84). The upper limits to the decays 3.06 → 0 and 3.84 → 0.87 are, respectively, 2 and 5%. The lifetimes of ^{17}O*(3.06, 3.84) are 120^{+80}_{60} and < 25 fsec, respectively (1964AL11).
Excitation functions have been measured in the range E_{t} = 1.0 to 2.0 MeV for the p_{0}, p_{1}, p_{2}, p_{3} groups, the d_{0} and t_{0} groups and the α_{0} and α_{1} groups: the reactions appear to proceed primarily via a direct interaction mechanism (1964SC09). See also ^{16}N, and ^{13}C and ^{15}N in (1970AJ04).
Differential cross sections have been measured at E_{α} = 8.12 to 11.52 MeV (1969SC21; pγ_{1}), 12.9 to 24.9 MeV (1970ZE01; p_{0}, p_{1}), 13.0, 13.4, 14.25, 14.5 and 18.1 MeV (1969RO07: states with E_{x} < 7.6 MeV), 17.3 to 24.9 MeV (1970ZE01; p_{2}), 22.3 MeV (1963YA1C; p_{0}, p_{1}), 22.5 to 24.9 MeV (1970ZE01; p_{3}), and 26.8, 28.1 and 33.3 MeV (1961YA02; p_{0} → p_{3}). Using the (2J + 1) rule, J = 7/2, 9/2 or 11/2 for ^{17}O*(5.22). The previously reported states at E_{x} = 6.24 and 7.29 MeV were not excited, but ^{17}O*(6.97) is confirmed by the work of (1969RO07). The lifetime of ^{17}O*(0.87), measured by this reaction and by reaction 29, τ_{m} = (4.30 ± 0.21) × 10^{10} sec (1962GA15): see Table 17.7 (in PDF or PS). See also (1959AJ76) and ^{18}F in (1972AJ02). At E_{α} = 22.9 MeV, the sequential decay (reaction (b)) appears to take place via a number of ^{17}O states with 8.46 ≤ E_{x} ≤ 13.57 MeV. Those involved are believed to have J ≥ 5/2, Γ_{α}/Γ ≥ 0.6 (1969BA17). See also (1968KU1C).
The excitation function has been measured for E_{d} = 0.5 to 5.3 MeV. Above E_{d} = 1.0 MeV, pronounced peaks are observed, presumably to be ascribed to numerous overlapping resonances (1958WE31). See also (1970MU1H). Polarization measurements (n_{0} group) are reported at E_{n} = 1.6 to 3.0 MeV (1966BR12), 2.65 MeV (1966BU09), 2.75 MeV (1969BU19), 3.09 to 3.83 MeV (1968ME15) and 4.35 and 5.50 MeV (1967BU16). See also (1966BR1E). See also ^{16}O.
The excitation curve has been obtained for E_{d} = 0.3 to 2.7 MeV. There is some resonance structure at E_{d} = 1.3 and 1.9 MeV [^{17}O*(15.2, 15.7)] (1957BO04). See also ^{16}N.
The α_{0} yield curve for E_{d} = 0.8 to 1.8 MeV indicates two resonances at E_{d} = 1.06 and 1.25 MeV [Γ ≈ 100 and 200 keV, respectively], attributed to an ^{17}O state at E_{x} = 14.98 MeV [J^{π} = 5/2^{+}] and to one or more ^{17}O states at E_{x} = 15.15 MeV [J^{π} = 5/2^{} or 7/2^{}] (1966TI03). In the range E_{d} = 1.2 to 2.5 MeV a broad maximum is observed in both the α_{0} and α_{1} yields at E_{d} ≈ 1.7 MeV (1965MA59). See also (1959FI30).
Not reported.
At E(^{3}He) = 18 MeV, many ^{17}O states with E_{x} < 11.6 MeV have been observed. The levels at 5.70 MeV (7/2^{}), 7.38 MeV (5/2^{}) and 11.08 MeV (1/2^{}; T = 3/2) are particularly strongly populated (1969ME1K). See also (1965SE01, 1968BE1Y, 1968SE1C). At E(^{3}He) = 8.4 MeV a T = 1/2 state at E_{x} = 11.02 MeV is excited (1970MC02): see also reaction 43 and Table 17.9 (in PDF or PS). See also (1963PA01) and (1969BA1Z).
At E_{α} = 45.4 MeV, the deuteron spectrum is dominated by the groups corresponding to states with E_{x} = 7.742 ± 0.020 and 9.137 ± 0.030 MeV. These states are assigned J^{π} = (11/2^{}) and (9/2^{}), respectively and arise from a dominant (d_{5/2})^{2}_{5}p^{1}_{1/2} configuration. Angular distributions were measured as well for the deuterons corresponding to ^{17}O(0) and to states with E_{x} = 0.87 ± 0.05, 5.208 ± 0.030, 5.690 ± 0.030, 7.367 ± 0.030, 8.459 ± 0.030, 8.890 ± 0.030 and 9.814 ± 0.030 MeV. In addition the excitation of states with E_{x} = 3.85 ± 0.05, 4.57 ± 0.05 and 8.147 ± 0.030 MeV is also reported (1969LU07). See also (1962HA40, 1966RI04) and (1963GL1C; theor.).
At E(^{11}B) = 115 MeV, the states at E_{x} = 7.7 and 9.1 MeV [J^{π} = 11/2^{} and 9/2^{}, respectively] are strongly populated. as in the ^{15}N(α, d)^{17}O reaction (1967PO1E). See also (1966PO1E, 1967VO1A).
Capture γrays with E_{γ} = 870 ± 5, 1088 ± 5, 2180 ± 25 and 3271 ± 15 keV, from the transitions to and decay of ^{17}O*(0.87, 3.06), are reported by (1964JU05). See also (1969HO1X). Astrophysical considerations are discussed by (1968FOZY).
The scattering amplitude (bound) is a = 5.80 ± 0.05 fm (1965DO14). The coherent scattering cross section is 4.23 ± 0.07 b (1964ST25). See also (1961WI1A, 1965RA15, 1969BA1P). Recent cross section and angular distribution measurements are listed in Table 17.10 (in PDF or PS). Cross section data are summarized in (1964ST25), while angular distribution data are displayed in (1970GA1A). See also (1968AL1G). A large number of resonances have been observed for E_{n} ≤ 11.5 MeV: these are displayed in Table 17.11 (in PDF or PS) (1960TS02, 1961FO07, 1967JO12, 1968DA1F, 1968JO1F, 1969DA13, 1970BO30, 1970FO03) and (1959AJ76, 1964ST25). See also (1966LI03). Recent highresolution cross section measurements and phaseshift analyses have led to a much better understanding of the ^{17}O level structure: see (1967JO12, 1970FO03) for a general review of the work on this reaction. See also (1960PE02, 1961GO1H, 1963KU1F), (1968AL1G) and (1959AU1A, 1960CO1A, 1960FO14, 1960MI1B, 1963JO1D, 1963KA27, 1963LU10, 1963PI03, 1965GA1F, 1965SL1B, 1966AG1A, 1966GA1L, 1967GR1J, 1967RE1C, 1967SC1E, 1967SC1H, 1967UN1A, 1968FO1D, 1969IW1A, 1969IW1C, 1969MA2B, 1970CO1U, 1970MU1C, 1970WA1J; theor.). Polarization measurements have been carried out for E_{n} = 0.2 to 3.5 MeV: see Table 17.10 (in PDF or PS) (1962BE1C, 1962EL01, 1962MA05, 1962OT01, 1963GL1D). See also the reviews by (1963HA1G, 1963PI03, 1966DA1B, 1966RO1B) and (1967BE1F; theor.)
Recent cross section measurements are listed in Table 17.10 (in PDF or PS). The cross sections for production of 6.13 and (6.92 + 7.12) γrays in the range E_{n} = 6.5 to 10 MeV show a number of resonances: see Table 17.12 (in PDF or PS) (1969HAZE). See also (1970SU01).
The cross section has been measured for E_{n} = 17 to 37 MeV (1961BR1A). See also (1964HE18).
Recent crosssection measurements are listed in Table 17.10 (in PDF or PS). Resonances are reported at 11.8 and (15.2) MeV (1962DE13) and at 13.50 ± 0.01, 14.10 ± 0.01 and 15.10 ± 0.05 MeV (1961SE02, 1962SE1F). See also (1958RO1A, 1969BR1F), (1959AJ76, 1960BU1C, 1963LE1D, 1963SH1C, 1966JE1B, 1968AL1G) and (1964DU1B; theor.).
See (1967VA12) and ^{15}N in (1970AJ04).
The cross section has been measured from threshold to 20 MeV: see (1959AJ76) and Table 17.10 (in PDF or PS). All of the ^{17}O levels observed in the inverse reaction ^{13}C(α, n)^{16}O from ^{17}O* = 7.95 to 9.95 are also observed in this reaction: see Table 17.6 (in PDF or PS) (1955SE1A, 1957WA46, 1963DA12). (1963BO1E) also report a broad maximum at E_{n} ≈ 16 MeV. See also (1965FU1E), (1960BU1C, 1963CH1C, 1966JE1B) and (1964GA1A; theor.).
Angular distributions of the protons to many ^{17}O states have been studied for E_{d} = 0.3 to 26.3 MeV: see Table 17.13 (in PDF or PS) (1959HA29, 1961HA19, 1961KE01, 1962MA25, 1963AL04, 1963AM1A, 1963YA03, 1964AM1A, 1964SC12, 1964TE1C, 1965DE1N, 1965GA1A, 1965LO02, 1965MO16, 1966AL09, 1966GA09, 1966SC09, 1967AL06, 1967OG1A, 1968DI06, 1968HO23, 1968NA06, 1968NG1B, 1969TH04, 1970DA14). See also (1969CO12, 1970CO1P) and ^{18}F in (1972AJ02). (1970VI03) report a DWBA calculation to the unbound 3/2^{+} state at E_{x} = 5.08 MeV. The width of the corresponding neutron resonance [E_{n} = 1.00 MeV: see reaction 23] is determined to be 67 keV from the magnitude of the cross section. ^{17}O levels derived from proton spectra measurements are displayed in Table 17.14 (in PDF or PS) (1951BU1A, 1957BR82, 1965GA1A). The lifetime of ^{17}O*(0.87) is 258.6 ± 2.6 psec: see Table 17.7 (in PDF or PS) (1960KA10, 1963LO03, 1964BE15, 1965AL14, 1965MC10, 1967BI05, 1969GO04). E_{γ} = 870.81 ± 0.22 keV (1966WI01), 870.5 ± 2.0 keV (1952TH24); the internal conversion coefficient is consistent with E2 (1952TH24).

The angular distribution of elastically scattered protons has been studied at E_{p} = 11 MeV (1967AL06). At E_{p} = 29 MeV, the odd parity states ^{17}O*(3.84, 4.55, 5.22, 5.70, 7.75) are strongly populated (R. Mendelson, private communication). See also ^{18}F in (1972AJ02) and (1969IC02; theor.).
The elastic angular distribution has been measured at E(^{3}He) = 17.3 MeV (1968HA30). See also (1969HA1U, 1969MA1G).

See (1963FU06).
Angular distributions have been measured at E_{p} = 17.6 MeV (1961LE1A, 1963LE03; d_{0}, d_{1}, d_{2}), 18.2 MeV (1967LU05; d_{0}, d_{1}, d_{2}, d_{3}) and at 27 and 31 MeV (R. Mendelson, private communication; d_{0} → d_{8} and ^{17}O*(11.08)). ^{17}O*(3.06, 5.38) contain most (> 80%) of the p_{1/2} and p_{3/2} hole strength respectively (R. Mendelson). See also (1969IG1A, 1970BO1K, 1970HI15; theor.).
Angular distributions of the tritons corresponding to ^{17}O*(0, 0.87, 3.84, 4.55, 5.08, 5.38) have been studied at E_{d} = 15 MeV (1961AR06). See also (1961VL02) and (1963OG1A, 1963RO12, 1968KA1E, 1970BO1K; theor.).
Angular distributions of alpha particles are reported by (1965WA1D; α_{0}, α_{1}) at E(^{3}He) = 2.68 to 6.47 MeV and by (1969DE06: see Table 17.15 (in PDF or PS)) at E(^{3}He) = 16 MeV. The T = 3/2 states reported by (1969DE06) are displayed in Table 17.15 (in PDF or PS) [the isospin identification is based on the enhanced excitation and the narrow widths of these states]. The branching ratios for transitions to ^{16}O*(0, 6.05) for ^{17}O*(11.08) [the first T = 3/2 state in ^{17}O] and for the analog state in ^{17}F are displayed in Table 17.9 (in PDF or PS): the ratios of the reduced widths are quite different in the two mirror nuclei (1970MC02). See also (1969BA1Z).
Angular distributions of the t_{0} and t_{1} groups are reported at E_{n} = 14.4 MeV by (1968AN1F, 1968RE07). See also (1964VA1E).
Angular distributions have been measured at E_{p} = 30.5 MeV (1967CO05, 1968CO1U: to ^{17}O*(0, 0.87)), 40 MeV (1966BR1X, 1966HO1F: to ^{17}O*(0, 0.87, 3.06, 3.84)) and 46 MeV (1969HU1H, 1970HU1J: to ^{17}O*(0, 0.87, 3.06)). The E_{p} = 30.5 MeV distributions have been compared by (1968CO1U) with those from the mirror (p, t) reaction.
Observed alpha groups are displayed in Table 17.14 (in PDF or PS) (1951BU1A, 1952WA1A, 1968BI09). Angular distributions have been measured at many energies in the range E_{d} = 0.3 to 27.5 MeV: see Table 17.16 (in PDF or PS) (1960HU10, 1961CI02, 1962FO02, 1962TA07, 1963HO1F, 1964JA08, 1964MA04, 1965CO07, 1965CO09, 1965ST14, 1966WE04, 1968BI09, 1968PR04, 1968TA02, 1969ME07, 1970BE68). The cross sections for formation of the lowlying states of ^{17}O obey the 2J + 1 rule, when it is cautiously applied: see (1965CO07, 1965CO09, 1968TA1N). Application of this rule, together with the results of reaction 29, leads to J^{π} = 5/2^{} for ^{17}O*(3.84) (1965CO07, 1965CO09). J for ^{17}O*(5.22) is found to be 3/2 (1968BI09). At E_{d} = 1.2 MeV, the γtransition (3.06 → 0.87) and (3.84 → 0) are observed: the absence of (3.06 → 0) is consistent with J = 1/2 for ^{17}O*(3.06) (1957MU1A). See also (1960KR02, 1960RI05, 1969LI22, 1970BI1D), (1969DA1L) and (1963MI1E; theor.).
At E_{α} = 42 MeV, angular distributions are reported for the ^{6}Li ions corresponding to ^{17}O*(0, 0.87) (1968MI05).
At E_{n} = 14.1 MeV, angular distributions are reported for the αparticles, corresponding to ^{17}O*(0, 0.87) (1966MC14). See also (1959BE66, 1966CE03, 1969KA1D).
