Model space dimensionalities for multiparticle fermion systems

Title of program: SU2DIMPH
Catalogue Id: AABN_v1_0

Nature of problem
A menu driven program for determining the dimensionalities of fixed-(J) (or (J,T)) model spaces built by distributing identical fermions (electrons, neutrons, protons) or two distinguishable fermion types (neutron-proton, isospin formalisms) among any mixture of positive and negative parity spherical orbitals is presented. The algorithm, built around the elementary difference formula d (J) = d(M=J) - d(M=J+1), takes full advantage of M -M and particle-hole symmetries. A 96K version of the progra ...

问题属性
本程序为菜单驱动程序（menu-driven program），可用于计算固定-(J)（或(J,T)）模型空间的维度。此类模型空间的构建方式为：将全同费米子（fermion，包括电子、中子、质子），或是两类可区分费米子（中子-质子体系、同位旋形式体系（isospin formalism））填充至正宇称（positive parity）与负宇称（negative parity）球形轨道（spherical orbital）的任意混合组态中。本程序所采用的算法以基础差分公式 $d(J) = d(M=J) - d(M=J+1)$ 为核心，可充分利用$M$对称性与粒子-空穴对称性（particle-hole symmetry）。本程序的96K内存版本……
