Description

High-spin states in 124Ba were populated via the 94Zr(34S, 4n)124Ba and 110Cd(16O, 2n)124Ba reactions at 145 MeV and 60 MeV, respectively. The yrast band has been extended to 34 ℎ and seven side bands have been observed. Gamma-ray angular distributions with respect to the nuclear spin axis have been used along with directional correlation (DCO) ratios to establish spins and multipolarities. The competing πh11/2 and νh11/2 crossings in this region are investigated and an interpretation of the observed crossings is proposed within the framework of the cranked shell model (CSM) and total routhian surface (TRS) calculations.
