核-粒子-空穴系统中的手征

Signatures of chirality in the core-particle-hole systems

S. G. Rohozinski, L. Prochniak, Ch. Droste, K. Starosta

摘要:

奇-奇原子核被视为核-粒子-空穴系统。核心由玻尔哈密顿量描述。不同的集体潜力的核心进行了研究。假设奇粒子和空穴处于对称的[质子h11/2]x[中子空穴h11/2]组态。奇-奇核谱中的手征的签名进行了观察。在核-粒子-空穴系统中出现手性特征的充分条件是核的α对称性,前提是奇价粒子的粒子-空穴构型是对称的。

英文摘要:

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.
