Abstract

The symplectie shell model, which incorporates vertical (2nh̵ω; n = 1, 2…) major shell configuration mixing as dictated by a quadrupole interaction, is augmented with horizontal (0ħω) mixing induced by realistic single-particle energies and a monopole-pairing interaction. The excitation spectrum and B(E2) rates of the 20Ne ground band are accurately reproduced without the use of an effective charge. The degree of horizontal and vertical mixing is found to be on the order of 20% in the ground state and up to as much as 50% for the 8+ level.

    These considerations motivate us to develop and investigate a novel model, the ab initio symmetry-adapted no-core shell model (SA-NCSM) [18], which, by taking advantage of symmetries inherent to the nuclear dynamics [19–22], can provide access to heavier nuclei and larger model spaces essential to accommodate collective, deformed, and cluster substructures [23–26,22,27–32].
