Codes for the combinatorial calculation of few quasiparticle state densities in spherical and deformed nuclei

Abstract
The codes for combinatorial calculation of few quasiparticle state and level densities are presented. The calculations are performed in the space of the shell-model single particle states and include pairing interaction explicitly. The spin and parity distributions of quasiparticle states are also provided. The calculations can be restricted to the states with all quasiparticles being bound.

Title of program: ICAR AND CONV
Catalogue Id: AAXS_v1_0

Nature of problem
The codes calculate combinatorially state and, for spherical nuclei also, level densities characterized by a fixed number of quasiparticles in terms of the shell-model and the BCS theory. The spin and parity distributions are provided. The calculations can be done with or without pairing interaction taken into account and they can be restricted to bound states only to obtain the densities used in the statistical multi step compound model. An option for the calculation of the pairing strength par ...

摘要
本文提供了少量准粒子态与能级密度的组合计算代码。计算基于壳模型（shell-model）单粒子态空间展开，并显式引入对相互作用。同时提供了准粒子态的自旋与宇称分布。计算可限定于所有准粒子均为束缚态的情形。

程序名称：ICAR与CONV
目录编号：AAXS_v1_0

问题属性
本代码基于壳模型与BCS（Bardeen-Cooper-Schrieffer）理论，以组合方式计算具有固定准粒子数的核态与能级密度，适用于球形原子核，并提供自旋与宇称分布。计算可选择是否考虑对相互作用，亦可仅限定于束缚态，以获取统计多步复合模型所需的能级密度。此外还提供了对力强度参数计算的可选功能……
