Nature of problem:
The program is designed to calculate wavefunctions and energies of nucleons up to the 2s 1d shell using the Hartree-Fock method. The two- body interaction is a sum of two gaussian potentials with spin, isospin and space exchange terms. The kinetic energy of the centre of mass Tcm is subtracted but the coulomb interaction is neglected. A one-body potential Cl-s may be added to the kinetic energy. A cartesian harmonic oscillator basis is used, with independent omegax, omegay, omegaz constants for each of the coordinate axes.

Solution method:
The program calculates a self-consistent nuclear field and determines orbital energies and wavefunctions of the nucleus.

The basis used for the description of the spacial part of the wavefunction includes the ten basis elements of the 1s, 1p, 2s 1d deformed shells and therefore the program may be used only for light nuclei. Orbitals must be eigenstates of parity but they may have no other symmetry.
