Abstract

One of the enticing manifestations of broken symmetries in atomic nuclei is the chiral doublet bands. We investigate such bands in ¹³⁶Pm and ¹³⁸Pm, to understand the underlying geometries and their correlations with the single-particle configurations. We identify such correlations leading to vibrational or static nature of chirality. Chirality withstands higher spins in ¹³⁶Pm, unlike ¹³⁸Pm. Our present calculations for ¹³⁸Pm, confirm the newly assigned spin and parity 9⁺ state as band-head of the yrast band, based on {πh_11/2⊗νh_11/2} configuration.
