Calculation of energy levels with the hybrid multi-determinant method in the fp region / G. Puddu. - In: THE EUROPEAN PHYSICAL JOURNAL. A, HADRONS AND NUCLEI. - ISSN 1434-6001. - 34:4(2007), pp. 413-415.
Abstract:
We compare the recent exact and coupled-cluster calculations (Phys. Rev. Lett. 98, 112501
(2007)) of energy levels using the GXPF1A Hamiltonian modified with variable shell gap with the cor-
responding results obtained with the hybrid multi-determinant scheme. We show that the hybrid multi-
determinant scheme is highly cost-efficient and very accurate for several angular momenta and variable
shell gap of the f5/2, p3/2, p1/2 shells relative to the f7/2 shell.
