Abstract

Doppler-shift measurements of γ-rays from the 31P(p,γ)32S reaction lead to the mean lifetimes τm = 260±80, 50±13, 170±100, 250±50, 68±12, 61±15 and > 1000 fs for the levels 32S∗ = 2.237, 4.287, 4.698, 5.012, 5.553, 6.226 and 6.621 MeV, respectively. The experimental electromagnetic transition rates are compared with those calculated with the asymmetric model of Davydov and Filippov. The level schemes of 16O, 24Mg and 32S have analogous characteristics.
