GENERAL: See (1977AJ02) and Table 17.22 [Table of Energy Levels] (in PDF or PS).

Theory and reviews:(1975BE56, 1977CE05, 1978GU10, 1979BE1H, 1979WO07).

Other topics:(1981GR08).

Mass of ¹⁷Ne: The mass excess adopted by (1977WA08) is 16.478 ± 0.026 MeV, based on unpublished data. We retain the mass excess 16.48 ± 0.05 MeV based on the evidence reviewed in (1977AJ02).

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 J^π = 3/2^-, 3/2^- and 1/2^-: see Table 17.23 (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 (1978RA2A).
