beta decay of In-132 and spectroscopy of Sn-132 and Sb-131 with the GRIFFIN spectrometer

Spectroscopy of doubly magic Sn-132(50)82 has been performed with the GRIFFIN spectrometer at TRIUMF-ISAC following the beta decay of In-132(49)83. The analysis has allowed for the placement of a total of 70 transitions and 29 excited states in Sn-132. Detailed spectroscopy has also been performed on Sb-131, resulting from the beta decay of Sn-131, produced from the beta-delayed neutron decay of In-132. Measurement of gamma rays in both Sn-131 and Sb-131 has led to the determination of the beta-delayed neutron emission probability P-n from In-132. This is the first time that P-n has been measured for this nucleus by using y spectroscopy, and the new value of 12.3(4)% is consistent with the most recent beta-n counting experiment. Additionally, y-y angular correlations have been performed in Sn-132, supporting the spin assignments of several excited states. Novel ab initio calculations are presented which describe several of the excited states, and these are compared with the experimental spectrum.
