Shell model study of /sup 40/S(. beta. /sup -/)/sup 40/Cl and the energy levels of /sup 40/Cl

Journal Article · · Phys. Rev. C; (United States)
;

Shell-model calculations are performed for the odd- and even-parity states of /sup 40/Cl and the 0/sup +/ /sup 40/S ground state. The /sup 40/Cl odd-parity states and the /sup 40/S 0/sup +/ levels were considered in full (2s,1d)/sup 21/(1f,2p)/sup 3/ and (2s,1d)/sup 20/(1f,2p)/sup 4/ configurational spaces, respectively. For the /sup 40/Cl even-parity states it was necessary to use a highly truncated (2s,1d)/sup 20/(1f,2p)/sup 4/ configurational space. Besides energy spectra and binding energies, observables calculated are first-forbidden and allowed ..beta../sup -/ decay of /sup 40/S, ..gamma.. transitions in /sup 40/Cl, and one-body density overlaps of the odd-parity states of /sup 40/Cl with the /sup 40/Ar ground state. The results are compared to experiment. For example, the half-life of /sup 40/S is predicted to be in the range 6.2--16.6 s (depending on the assumed level scheme) as compared to the experimental value of 8.8 +- 2.2 s.
