Abstract
Total binding energies for nuclei with are obtained from a realistic effective no-core Hamiltonian, , using moment methods. The lowest few moments of are evaluated in an oscillator model space of four major shells. These moments are then used to determine a number of continuous and discrete density of states functions, each of which yields an estimate for the ground state energy. The adjustable discrete density of states functions which we introduce are based upon realistic single-particle Hamiltonians. With a reasonable selection of moment method ingredients we obtain good agreement between theory and experiment for relative binding energies within each chain. The most stable isobar is correctly predicted in all cases and Coulomb energy differences are in close agreement with experiment. Thus, the valley of stability is well reproduced in this approach with a simple overall shift in absolute binding energies for each chain.
