Abstract
For pt.X see A. Watt et al., ibid., vol.6, no.1, p.35-46 (1980). Least-squares fits of sd-shell effective interactions (EI) are performed in terms of relative matrix elements (RME). The energy spectra of a number of nuclei in the mass range 18 to 21 are calculated using the RME representation of the EI; they agree satisfactorily with experiment. The results suggest that translational invariance is a dominant feature of the EI considered.Keywords
