Nature of problem:
PROJ calculates energies of the rotational band generated by a nuclear wave function PhiM which is an eigenstate of JZ with the eigenvalue M. The nuclear wave function may be obtained by using program HARFOCK (CPC 3 (1972) 22). The two-body interaction must be a sum of two gaussian potentials with arbitrary spin, isospin and space-exchange terms.
The energy of each rotational state is evaluated by the Peieris-Yoccoz formula. For each value of the rotation angle, Beta, chosen by the integration program, the matrix elements occuring are evaluated.
The geometrical basis includes the 1s, 1p and 2s, 1d deformed shells. The program works with 40 occupied and unoccupied orbitals. The interaction must be expotential. The c.m. two-body elements are taken into account but the Coulomb interaction is neglected. Orbitals must be eigenstates of Jz and rz. M must be positive or equal to 0.
