Abstract: (Elsevier)

We analyse the momentum and density dependence of the ph interaction in self-consistent RPA calculations of electromagnetic reactions with Skyrme forces. First, we calculate the V 00 ph and V 01 ph spin-isospin components in nuclear matter for an SK3 interaction. At the nuclear surface, they have decreasing values with increasing q -values up to momenta q =3 fm −1 . As a second point, we show that the predictions of the 12 C(e, e') charge response at 400 MeV/ c remain practically unchanged when the zero-range quadratic momentum dependence of the SK3 interaction is replaced by the momentum dependence associated with a Yukawa short-ranged force.
