Nature of problem: Solution of self-consistent mean-field equations for weakly bound paired nuclei requires a correct description of asymptotic properties of nuclear quasiparticle wave functions. In the present implementation, this is achieved by using the single-particle wave functions of the Transformed Harmonic Oscillator, which allows for an accurate description of deformation effects and pairing correlations in nuclei arbitrarily close to the particle drip lines.
Solution method: The program uses axial Transformed Harmonic Oscillator (THO) single-particle basis to expand quasiparticle wave functions. It iteratively diagonalizes the Hartree-Fock-Bogolyubov Hamiltonian based on the Skyrme forces and zero-range pairing interaction until the self-consistent solution is found.
Restrictions: Axial-, time-reversal-, and space-inversion symmetries are assumed. Only quasiparticle vacua of even-even nuclei can be calculated.
Running time: 4 seconds per iteration on an Intel Xeon 2.8 GHz processor when using N_sh = 20
