GENERAL: See 17.26 [Table of Energy Levels] (in PDF or PS).

1. (a) 17Ne(β+)17F* → 16O + p	Qm = 13.928
(b) 17Ne(β+)17F → 13N + α	Qm = 8.711
(c) 17Ne(β+)17F	Qm = 14.529

The half-life of ¹⁷Ne has been reported as 109.0 ± 1.0 msec (1971HA05) and 109.3 ± 0.6 msec (1988BO39): the weighted mean is 109.2 ± 0.6 and we adopt it. The decay is primarily to the proton unstable states of ¹⁷F at 4.65, 5.49, 6.04 and 8.08 MeV with J^π = 3/2^-, 3/2^-, 1/2^- and 3/2^-, but decay to alpha unstable states has also been observed: see 17.27 (in PDF or PS). The super-allowed decay to the analog state [¹⁷F*(11.20)] has log ft= 3.29^+0.04_-0.07. The character of the decay leads to J^π = 1/2^- for ¹⁷Ne_g.s. (1971HA05). See 17.6 (in PDF or PS) for a comparison of the mirror ¹⁷N and ¹⁷Ne decays and 17.16 (in PDF or PS) for the decay of ¹⁷F*(11.20). See also (1986AJ04), and see the recent analysis of GT beta-decay rates of (1993CH06).
