Abstract：
Starting from the shell model configurations and the effective nucleon-nucleon interactions,a microscopic approach is applied to study high-spin states for the isotopes ¹²⁶Ba,¹²⁸Ba and ¹³⁰Ba.The low-lying states and the band built upon aligned (h_11/2)proton pair configurations are considered.Energy levels and backbendings are reproduced well.For the yrast band,the dependence of the strength of interband interaction on the coupling operator is discussed.
