Extrapolation method in shell model calculations with a deformed basis

摘要: An extrapolation method in shell model calculations with a deformed basis is presented, which uses scaling property of energy and variance for series systematically approximated wave functions to the true one. Such are given by variation-after-projection concerning full angular momentum projection. This needs variance, amounts calculation expectation value square Hamiltonian H{sup 2}. We present evaluate this matrix element show that large reduction its numerical computation can be done taking advantage time-reversal symmetry. The tests presented fp-shell realistic residual interaction.
