Abstract
Scaling the system size of the interacting boson model-1 (IBM-1) into the realm of hundreds of bosons has many interesting applications in the field of nuclear structure, most notably quantum phase transitions in nuclei. We introduce IBAR, a new software package for calculating the eigenvalues and eigenvectors of the IBM-1 Hamiltonian, for large numbers of bosons. Energies and wavefunctions of the nuclear states, as well as transition strengths between them, are calculated using these values....

本程序源自贝尔法斯特女王大学（1969-2018年）所持有的CPC程序库。摘要部分指出，将相互作用玻色子模型-1（IBM-1）的系统尺寸扩展至数百个玻色子的范畴，在核结构领域具有诸多有趣的应用，尤其是核内的量子相变现象。为此，我们推出了IBAR这一新型软件包，旨在计算IBM-1哈密顿量的本征值和本征向量，适用于大量玻色子。通过这些值，可以计算出核态的能量和波函数，以及它们之间的跃迁强度。程序名称：IBAR，目录编号：AELI_v1_0。问题描述：构建和求解大哈密顿矩阵，使用d玻色子创建算符的约化矩阵元。本程序在Mendeley Data的CPC存储库中的版本为：AELI_v1_0；IBAR；10.1016/j.cpc.2011.12.024
