Theoretical and empirical d+He-4 potentials: an anomalous Majorana component?

摘要

We have surveyed, with recalculation where required, existing empirical and RGM-derived local d-He-4 potentials in order to identify, in empirically derived potentials, features predicted by RGM. Qualitative consistency emerges, but the energy dependence of the Majorana central component of the d + He-4 interaction, as determined by inversion of RGM S-matrix, suggests a ratio of even-l to odd-l central potential (expressed in terms of volume integrals) of about 1.5 at E-lab = 10 Mev. The value of this ratio extracted from empirical potentials is much lower. (C) 2003 Elsevier B.V. All rights reserved. [References: 16]
