GENERAL: See (1982AJ01) and Table 17.20 [Table of Energy Levels] (in PDF or PS).

Theory and reviews: (1983ANZQ, 1983AU1B, 1985AN28).

1. (a) 17Ne(β+)17F* → 16O + p	Qm = 13.93
(b) 17Ne(β+)17F	Qm = 14.53

The half-life of ¹⁷Ne is 109.0 ± 1.0 msec (1971HA05). Earlier values (see (1971AJ02)) gave a mean value of 108.0 ± 2.7 msec. The decay is primarily to the proton unstable states of ¹⁷F at 4.70, 5.52 and 6.04 MeV with J^π = 3/2^-, 3/2^- and 1/2^-: see Table 17.21 (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 Table 17.3 (in PDF or PS) for a comparison of the mirror ¹⁷N and ¹⁷Ne decays and Table 17.11 (in PDF or PS) for the decay of ¹⁷F*(11.20). See also (1983RA29).
