Abstract

The high spin states of 79 Kr were studied via the 70 Zn (13 C , 4 n ) reaction to search for chiral doublet bands based on the three-quasi-particle configuration, πg9/22 ⊗ νg9/2-1. The 13 C beam of 65 MeV was provided by the 930 AVF Cyclotron at CYclotron and RadioIsotope Center (CYRIC) facility at Tohoku University. The triple coincidence γ rays were detected by the Hyperball2 array. The side band structure to the πg9/22 ⊗ νg9/2-1 yrast band has been identified in 79 Kr . Spin and parity assignments are made based on the DCO ratio and linear polarization analysis.
