Abstract

Spin-isospin dependent repulsion parameters of the effective particle-hole and Δ-hole interactions g ′ and g ′ Δ are estimated. It is pointed out that higher order effects enhance g ′ and g ′ Δ by about 10% and 20% respectively in nuclear matter. Its implications to the Δ-hole quenching mechanism of nuclear στ moments are discussed. A comment on the “ g ′ - g ′ Δ universality” assumption is made.
