A mathematically rigorous treatment of the antisymmetrized geminal power AGP model is given. The model is advocated as an extremely flexible tool for studying a wide variety of fermion systems, characterized by a single Slater determinant, on the one hand, or Yang's most highly correlated wave funct

Title of program: SU2DIMPH a case as d[(+1/2, +3/2, +5/2, +7/2 -11/2)" 26J = 2~,T 7] = 210, 442, 716, 722 found in the Ohw valence space Catalogue number: AABN of ~6Ba 70. The program calculates the total fixed-(J") or fixed~(J~r, T) Program obtainable from: CPC Program Library, Queen's Uni-dimensionality of a model space generated by distributing a versity of Belfast, N. Ireland (see application form in this issue) specified number of fermions among a set of input positive and negative parity (~r)spherical (j) orbitals [1]. The user is Computer: Installation: queried at each step to select among various options: IBM 3081-D24 Louisiana State University 1. Formalism -Identical particle, neutron-proton, isospin; DG MV/10000 Louisiana State University 2. Orbits -Number, + / -2 * / of all orbits; IBM-PC/XT Compliments of IBM Corporation 3. Limits -Minimum/maximum number of particles of each parity; Operating system: MVS/SP 1.3.3, AOS/VS and DOS 2.0 4. Specifics -Number of particles, +/-2 * J (total), 2 * 5. Continue -Same orbit structure, new case, quit. Programming language used: FORTRAN77 Though designed for nuclear applications (s-coupling), the High speed storage required: 116 Kbytes program can be used in the atomic case (LS-coupling) so long as half integer spin values (j = I ยฑ1/2) are input for the Peripherals used: disk, printer valence orbitals. Mutiple occurrences of a given j value are properly taken into account. A minor extension provides label-Number of lines in combined program and test deck: 973 ling information for a generalized seniority classification scheme [2]. The program logic is an adaptation of methods used in
