Photon absorption and scattering cross-sections by triaxial nuclei

Abstract
A FORTRAN routine is presented for the calculation of photon absorption and scattering cross-sections by triaxial nuclei in the energy region of the giant dipole resonance. The relevant formalism is based on the interacting-boson model of nuclear structure, also including the isospin degree of freedom.

Title of program: TRIAXI
Catalogue Id: ACGI_v1_0

Nature of problem
A group-theoretical formalism has been developed and implemented in a fast routine in order to deal with photon-induced reactions on triaxial nuclei in the energy region dominated by the giant dipole resonance (GDR), which typically ranges between 10 and 30 MeV. The present approach is based on the interacting boson model of nuclear structure, allowing for coupling between GDR and low-lying collective modes of the nucleus. Isospin degree of freedom can also be included in the calculations. The c ...

本文介绍了一种FORTRAN程序，用于计算三轴核在巨偶极共振（GDR）能量区域内的光子吸收和散射截面。该相关形式基于核结构的相互作用玻色子模型，并包括同位旋自由度。程序名称：TRIXI；目录编号：ACGI_v1_0。

问题描述：一种基于群论形式主义的快速程序已被开发并实施，以处理三轴核在受巨偶极共振（GDR）主导的能量区域内的光子诱导反应，该区域通常介于10至30 MeV之间。当前方法基于核结构的相互作用玻色子模型，允许巨偶极共振与核的低激发集体模式耦合。计算中亦能包含同位旋自由度。程序版本：ACGI_v1_0；TRIXI；参考文献：10.1016/0010-4655(92)90101-4。
