Abstract: (Elsevier)
The effective interaction between two nucleons inside nuclear matter is calculated microscopically for several densities and several temperatures, assuming it is given by the Brueckner g-matrix, derived from the separable Graz version of the Paris potential. Particular attention is paid to the temperature dependence and to the way of putting the effective interaction into a Skyrme functional. It is found that the latter task can be achieved with a very good accuracy and that the Skyrme coefficients are weakly and quadratically temperature dependent. The g -matrix issued from the Paris potential turns out to be rather different from the standard Skyrme forces in singlet odd states. The charge dependence is investigated through the study of neutron matter. The connection with the temperature dependence of the surface energy is also discussed.References(26)
