势能面映射法计算IBM的微观参数

Microscopic Calculation of IBM Parameters by Potential Energy Surface Mapping

I. Bentley, S. Frauendorf

摘要:

相干态技术用于生成模拟平均场能量表面的相互作用玻色子模型(IBM)哈密顿能量表面。这里提出的方法有一些显着的优势,比以前的工作。具体地说,这可以是一个完全的预测,不需要IBM参数的先验知识。该技术允许预测的低洼能谱和电磁跃迁率,这是天体物理学的兴趣。包括对氪、钼、钯、镉、钆、镝和铒核的测量结果和与实验的比较。

英文摘要:

A coherent state technique is used to generate an Interacting Boson Model (IBM) Hamiltonian energy surface that simulates a mean field energy surface. The method presented here has some significant advantages over previous work. Specifically, that this can be a completely predictive requiring no a priori knowledge of the IBM parameters. The technique allows for the prediction of the low lying energy spectra and electromagnetic transition rates which are of astrophysical interest. Results and comparison with experiment are included for krypton, molybdenum, palladium, cadmium, gadolinium, dysprosium and erbium nuclei.
