(See Energy Level Diagrams for 18Ne)
Complex reactions involving 18Ne:(1986HA1B).
The half-life of 18Ne is 1672 ± 8 msec: see (1978AJ03) and (1983AD03). The decay is primarily to 18F*(0, 1.04, 1.70). In addition there is an extremely weak branch [(2.07 ± 0.28) × 10-3%] to 18F*(1.08) [Jπ = 0-; T = 0] (1983AD03): see Table 18.21 (in PDF or PS) for the parameters of the decay. The parity mixing in the 18F*(1.04, 1.08) 0+ - 0- doublet has been studied by (1983AD03). See also (1982HE04). For the earlier work see, in particular, (1981AD01, 1981HA06). See also (1983AD1C, 1983AD1B, 1983AD1D, 1984AD1E, 1985AD1A, 1985BR29) and (1984HA58, 1986BR1X, 1986HA1Q, 1986TO1D, 1987KI03; theor.).
At E(10B) = 100 MeV the angular distribution to 18Ne*(3.38) [(d5/2)24+ state] which is preferentially populated has been studied. 18Ne*(1.89) is also observed. See (1983AJ01). See also (1983OS07; theor.).
Angular distributions have been studied at Eπ+ = 164 and 292 MeV [see (1983AJ01)] and at 48.3 MeV (1985AL15; to 18Neg.s.) and 100 to 292 MeV (1985SE08; to 18Neg.s.). The excitation functions for production of 18Ne*(0, 1.89) have been measured for Eπ+ = 80 to 292 MeV: see (1983AJ01, 1985SE08). See also (1984BA1B, 1985GIZX, 1986ANZY), (1985GI01; theor.) and the "GENERAL" section here.
Observed triton groups are displayed in Table 18.24 (in PDF or PS) as are Jπ derived from DWBA analysis of angular distributions: The 0+3 state, identified at Ex = 4.59 MeV, appears to have largely s21/2 configuration based on its large downward shift with respect to the analog state in 18O (1981NE09).
