^{17}N (1993TI07)(See Energy Level Diagrams for ^{17}N) GENERAL: See 2 [Electromagnetic Transitions in A = 1617] (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 ^{17}N states] (in PDF or PS). Theoretical papers and reviews:Energy spectra and wave functions of ^{17}N are calculated and the results used to predict ^{18}O(d, ^{3}He)^{17}N spectroscopic factors and electromagnetic transition rates (1989WA06). Selfconsistent calculations of light nuclei including ^{17}N are reviewed in (1990LO11). Production of ^{17}N in heavy ion collisions is discussed in (1986HA1B, 1987RI03, 1987YA16, 1989VOZM). See also (1986AN07, 1986PO06, 1991SK02, 1992KW01, 1992WA22). Experimental papers:Production of ^{17}N in heavy ion collisions or multinucleon transfer in collisions of light nuclei are discussed in (1986BI1A, 1987AN1A, 1987AV1B, 1987SA25, 1987VI02, 1989CA25, 1989SA10, 1989YO02).
The halflife of ^{17}N is 4.173 ± 0.004 sec. The decay is principally [see 17.5 (in PDF or PS)] to the neutron unbound states ^{17}O*(4.55, 5.38, 5.94) [J^{π} = 3/2^{}, 3/2^{}, 1/2^{}]. The nature of the decay is in agreement with J^{π} = 1/2^{} for ^{17}N_{g.s.}: see (1982AJ01). For a comparison of the ^{17}N and ^{17}Ne 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 γrays 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 E_{c.m.} = 1.45  6.10 are reported in (1990DA03).
Angular distributions have been studied to ^{17}N*(1.91, 2.53, 3.63, 4.01, 5.17) at E(^{6}Li) = 34 MeV and the results compared with those for the analog reaction to ^{17}O (reaction 20) (1983CU04).
Observed proton groups are displayed in 17.8 (in PDF or PS).
The giant resonance at E_{x} = 23.5 MeV decays to ^{17}N_{g.s.} and to the first three excited states of ^{17}N (1982BA03). See also ^{18}O in (1983AJ01).
Observed groups of ^{3}He ions are displayed in 17.7 (in PDF or PS). See also (1982AJ01) and ^{20}F in (1983AJ01). Shellmodel calculations of energy spectra and wave functions for ^{17}C and ^{17}N are presented in (1989WA06), and the results are used to predict spectroscopic factors for this reaction. Arguments are given for J^{π} assignments for states in ^{16}N below neutron threshold.
