Shell-model study of the N=82 isotonic chain with a realistic effective hamiltonian

L. Coraggio, A. Covello, A. Gargano, N. Itaco, T. T. S. Kuo

摘要:

我们已经进行了壳模型计算的偶数和奇数质量N=82同位素,专注于低能量状态。在含时简并链接图微扰理论的框架内,从由CD-Bonn核子-核子势导出的低动量相互作用出发,确定了单粒子能量和有效两体相互作用。这样,没有唯象输入进入我们的有效哈密顿量,其可靠性是由理论和实验之间的良好协议证明。

英文摘要:

We have performed shell-model calculations for the even- and odd-mass N=82 isotones, focusing attention on low-energy states. The single-particle energies and effective two-body interaction have been both determined within the framework of the time-dependent degenerate linked-diagram perturbation theory, starting from a low-momentum interaction derived from the CD-Bonn nucleon-nucleon potential. In this way, no phenomenological input enters our effective Hamiltonian, whose reliability is evidenced by the good agreement between theory and experiment.
