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).
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).
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).
