Abstract
The γ-rays following the β − decay of 40Cl have been investigated with Ge(Li) and Nal(Tl) detectors. The 40Cl sources were produced by fast-neutron bombardment of high-purity liquid argon samples. The half-life was measured to be 1.32 ± 0.02 min. Coincidence data for the prominent lines lead to a decay scheme accounting for 71 transitions, out of the 76 attributed to 40Ar, between 37 levels. The 40Cl β-ray branching was inferred from the relative γ-ray intensities. Evidence is found for 22 new β-branches. A previously reported strong β-group (20 %) to the first excited state is shown to have an intensity < 4 %. The log ft values support J π = 2 − for the ground state of 40Cl.
