17N (1993TI07)(See Energy Level Diagrams for 17N) GENERAL: See 2 [Electromagnetic Transitions in A = 16-17] (in PDF or PS), 17.2 [General Table] (in PDF or PS), 17.3 [Table of Energy Levels] (in PDF or PS) and 17.4 [Radiative transitions and lifetimes of 17N states] (in PDF or PS). Theoretical papers and reviews:Energy spectra and wave functions of 17N are calculated and the results used to predict 18O(d, 3He)17N spectroscopic factors and electromagnetic transition rates (1989WA06). Self-consistent calculations of light nuclei including 17N are reviewed in (1990LO11). Production of 17N in heavy ion collisions is discussed in (1986HA1B, 1987RI03, 1987YA16, 1989VOZM). See also (1986AN07, 1986PO06, 1991SK02, 1992KW01, 1992WA22). Experimental papers:Production of 17N in heavy ion collisions or multinucleon transfer in collisions of light nuclei are discussed in (1986BI1A, 1987AN1A, 1987AV1B, 1987SA25, 1987VI02, 1989CA25, 1989SA10, 1989YO02).
The half-life of 17N is 4.173 ± 0.004 sec. The decay is principally [see 17.5 (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.: see (1982AJ01). For a comparison of the 17N and 17Ne decays see 17.6 (in PDF or PS). For GT transition rates see (1983SN03) and (1983RA29) and references in (1986AJ04). See also the recent analysis of GT β decay rates of (1993CH06).
See (1988LA25).
Observed proton groups and γ-rays are displayed in 17.7 (in PDF or PS). 17.4 (in PDF or PS) shows branching ratio and lifetime measurements. Recent measurements of the cross section at Ec.m. = 1.45 - 6.10 are reported in (1990DA03).
Angular distributions have been studied to 17N*(1.91, 2.53, 3.63, 4.01, 5.17) at E(6Li) = 34 MeV and the results compared with those for the analog reaction to 17O (reaction 20) (1983CU04).
Observed proton groups are displayed in 17.8 (in PDF or PS).
The giant resonance at Ex = 23.5 MeV decays to 17Ng.s. and to the first three excited states of 17N (1982BA03). See also 18O in (1983AJ01).
Observed groups of 3He ions are displayed in 17.7 (in PDF or PS). See also (1982AJ01) and 20F in (1983AJ01). Shell-model calculations of energy spectra and wave functions for 17C and 17N are presented in (1989WA06), and the results are used to predict spectroscopic factors for this reaction. Arguments are given for Jπ assignments for states in 16N below neutron threshold.
