The Beta Decay of 32Cl

POSTER

Abstract

$^{\mathrm{32}}$Cl is a neutron-deficient isotope with a $\beta $-decay half-life of 298 ms and a spin and parity of 1$^{\mathrm{+}}$. It lies close to stability; therefore it can be produced in large quantities at rare isotope beam facilities making its decay relatively straightforward to study. Previous measurements of $^{\mathrm{32}}$Cl $\beta $-delayed $\gamma $ rays have yielded $\beta $-decay schemes including allowed $\beta $ decay transitions. In this study, we present the results of a more sensitive measurement of $^{\mathrm{32}}$Cl beta decay using the CloverShare array of high-purity germanium detectors at the National Superconducting Cyclotron Laboratory. By acquiring the highest-resolution and highest-statistics $^{\mathrm{32}}$Cl $\beta $-delayed $\gamma $ ray data set to date, this experiment has allowed for the observation of several $\gamma $ ray transitions that had only been previously observed in nuclear reaction experiments. A more complete decay scheme has been constructed, including the first observation of forbidden Gamow-Teller transitions in $^{\mathrm{32}}$Cl $\beta $ decay.
