Topics on the Nucleon-Nucleon Interaction

Abstract

<p> Some aspects of the nucleon-nucleon interaction are investigated. Phase-equivalent families of rank-two separable potentials are derived by inverting the on- shell phaseshifts. The off-shell properties of these potentials are examined and shown to be well behaved. These and additiona l pairs of phase-equivalent local and separable potentials are included in a proton-proton bremsstrahlung calculation. In particular, the off-shell dependence of the cross sections is shown to be small. </p>
