Signatures of chirality in the core-particle-hole systems

Abstract

An odd-odd nucleus is treated as the core-particle-hole system. The core is described by the Bohr Hamiltonian. Different collective potentials of the core are investigated. The odd particle and hole are assumed to be in the symmetric [proton h11/2]x[neutron hole h11/2] configuration. Signatures of chirality in the odd-odd nucleus spectra are observed. The sufficient condition for the appearance of signatures of chirality in the core-particle-hole system is the alpha-symmetry of the core provided the particle-hole configuration of the odd valence particles is symmetric.
