Abstract

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{stroke} 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 πh_{11 2} and νh_{11 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.
