Central and noncentral components of the preedom-wildenthal interaction

Abstract

The influence of the various components of the Preedom-Wildenthal interaction - viz., central, tensor, spin-orbit (LS) and antisymmetric spin-orbit (ALS) - on properties of A = 20,21 nuclei is investigated. The effects of the LS and ALS components on the one hand and of the central and tensor components on the other hand are found to be very similar. It turns out to be possible to remove the ALS component in favour of an enhanced LS component without spoiling the agreement with experiment.
