Electromagnetic transition strengths in 33S

Abstract

An experiment using the Doppler Shift Attenuation Method was performed for33S at Laboratori Nazionali di Legnaro using the multi-detector array GASP. Excited states were populated in the fusion-evaporation reaction 24Mg(14N,α p)33S. The data were analyzed using the Differential Decay Curve Method with gates set on the shifted component of a directly feeding transition thus eliminating the problem of the unobserved feeding. Reliable and precise lifetimes were determined and the data derived for the reduced transition probabilities are going to be compared to the predictions of shell model calculations.
