Abstract
A class of approximate interactions ZRA, having contact density dependence and microscopically derived density independent part, is constructed. Such an approximation retains all physical virtues of non-contact density dependent interactions and simplifies numerical calculations considerably. ZRA is tested and compared with similar interactions in nuclear matter and in s-d shell. The spurious “selfscreening” rearrangement termS α and a shape transition in32S are studied.
