Abstract

Methods which derive oscillator matrix elements directly from the nucleon-nucleon phase shifts usually use a zero order potential for a DWBA type approximation. Such a method is extended to include also hard- and soft-core potentials as zero order approach. The influence of the resulting correction terms is studied in Brueckner-Hartree-Fock calculations for 16O. Although realistic potentials (Hamada-Johnston and Reid soft-core) are used as reference potentials in DWBA, the effect of these corrections turns out not to be negligible, yielding, about 0.7 MeV per nucleon additional binding energy in 16O.
