M. Baldo et Ls. Ferreira, DEPENDENCE OF THE LANDAU PARAMETERS ON THE SINGLE-PARTICLE POTENTIAL, Physical review. C. Nuclear physics, 50(4), 1994, pp. 1887-1892
We investigate the relevance of the single particle potential on the t
heoretical determination of the Landau parameters within the Brueckner
-Bethe-Goldstone theory of symmetric nuclear matter. In particular we
study the influence of the choice of the single particle potential on
their overall trend as well as the fulfilment of the sum rules. At the
two-hole level of approximation the single particle continuous choice
and the corresponding effective mass give Landau parameters which bes
t satisfy the sum rules. However, the spin-isospin parameter G'0 appea
r small in comparison with phenomenology. A good value can be obtained
by a slight enhancement of the effective mass, with respect to the Br
uechner value, still keeping the other Landau parameters within the ph
enomenological boundaries and fulfilling the sum rules fairly well.
