High-spin intruder band in ${}^{107}$In

Abstract

High-spin states in the neutron deficient nucleus ${}^{107}$In were studied via the ${}^{58}$Ni(${}^{52}$Cr, 3p) reaction. In-beam ${\hat{I}}^3$ rays were measured using the JUROGAM detector array. A rotational cascade consisting of ten ${\hat{I}}^3$-ray transitions which decays to the 19/2${}^{+}$ level at 2.002 MeV was observed. The band exhibits the features typical for smooth terminating bands which also appear in rotational bands of heavier nuclei in the A$\sim$100 region. The results are compared with Total Routhian Surface and Cranked Nilsson-Strutinsky calculations.
