17N (1982AJ01)(See Energy Level Diagrams for 17N) GENERAL: See (1977AJ02) and Table 17.1 [Table of Energy Levels] (in PDF or PS). Theoretical papers and reviews:(1978KR19, 1979AL22, 1979BE1H, 1979BO22, 1980MI1G, 1981OS04). Experimental papers:(1977AR06, 1977BA44, 1978GE1C, 1978KO01, 1980OLZW, 1981FR1D).
The half-life of 17N is 4.173 ± 0.004 sec (1976OH05, 1972AL42). See also (1971AJ02). The decay is principally [see Table 17.2 (in PDF or PS)] to the neutron unbound states 17O*(4.55, 5.38, 5.94) [Jπ = 3/2-, 3/2-, 1/2-]. The nature of the decay is in agreement with Jπ = 1/2- for 17Ng.s. (1973PO11, 1976AL02). For a comparison of the 17N and 17Ne decays see Table 17.3 (in PDF or PS) (1976AL02, 1976OH05).
† See (1977AJ02) for several other reactions leading to 17N. Angular distributions are reported at E(9Be) = 5.0 MeV to 17N*(0, 1.37, 2.53) (1977YO02).
Observed proton groups and γ-rays are displayed in Table 17.4 (in PDF or PS). Table 17.5 (in PDF or PS) shows branching ratio and lifetime measurements (1974RO27, 1974RO28).
Observed proton groups are displayed in Table 17.6 (in PDF or PS). See also (1971AJ02).
At Eα = 65 MeV 17N*(3.13, 3.63) are the only states of 17N which are strongly populated (1978JA10).
At E(13C) = 105 MeV 17N*(3.13, 3.63) are strongly populated (1979RA10).
See 18O in (1978AJ03).
See (1976BA41) and 18O in (1983AJ01).
Observed groups of 3He ions are displayed in Table 17.4 (in PDF or PS): the 1/2- ground state contains the full 1p1/2 strength. The strength of all other observed l = 1 transitions is assumed to originate from pickup from the 1p3/2 shell (1977MA10). Analyzing powers have been obtained at Ed-bar = 52 MeV to 17N*(0, 1.37, 1.85, 2.53, 5.51, 6.99) (1981MA14).
At Et = 3.5 MeV (1976GU14) have studied α - γ angular correlations and γ-ray branching ratios for the first six excited states of 17N: see Tables 17.4 (in PDF or PS) and 17.5 (in PDF or PS). See also (1971AJ02).
