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 |
