✦ Synopsis

Nature of physical problem

PROJ calculates energies of the rotational band generated by a nuclear wavefunction ' 1M which is an eigenstate of.12 with the eigenvalue M. DM may be obtained by using program HARFOCK [1].The two-body interaction must be a sum of two gaussian potentials with arbitrary spin, isospin and space-exchange terms.

Method of solution

The energy of each rotational state is evaluated by the Peierls-Yoccoz formula 12,31. For each value of the rotation angle, j3, chosen by the integration program, the matrix elements occurring are evaluated.

Restrictions on the complexity of the problem

The geometrical basis includes the is, ip and 2s, id deformed shells. The program works with 40 occupied and unoccupied orbitals. The interaction must be exponential. The cm. two-body elements are taken into account but the Coulomb interaction is neglected. Orbitals must be eigenstates ofJz and r~.Mmust be positive or equal to 0.
