RPA calculation of K+-nucleus cross-sections with a density-dependent Brueckner-Hartree-Fock NN interaction
J. C. Caillon, J. Labarsouque
Abstract
In the calculation of the K+-nucleus cross sections, the coupling of the mesons exchanged between the K+ and the target nucleons to the polarization of the Fermi and Dirac seas has been taken into account. This polarization has been calculated in the one-loop approximation but summed up to all orders (RPA approximation). For this calculation a density-dependent Brueckner-Hartree-Fock NN interaction providing a good description of both nuclear matter and finite nuclei has been used. The agreement with experiment is considerably improved.
