Detailed study of the decay ³¹Cl(βγ)³¹S

RADIOACTIVITY ³¹Cl(β⁺), (EC)[from ⁹Be(³⁶Ar, X), E=150 MeV/nucleon using A1900 Fragment Separator for Bρ, and Radio Frequency Fragment Separator (RFFS) for TOF at NSCL-MSU facility]; measured Eγ, Iγ, βγ- and βγγ-coin using Yale Clovershare array for γ detection, and plastic scintillator for β detection. ³¹S; deduced levels, resonances, J, π, β feedings, logft values, isospin mixing, ratio of thermonuclear reaction rates for ³⁰P(p, γ)³¹S reaction at T₉=0.1-0.4 for the newly discovered state at 6390 keV and the IAS at 6280 keV. Comparison with USDB and USDE shell-model calculations, and previous experimental results.
