Test of J-matrix inverse scattering potentials on photonuclear reactions of A=2,3,4 nuclei

摘要

This contribution reports on a recent calculation of the total photonuclear cross sections of H-2, H-3, He-3 and He-4 performed with the Lorentz Integral Transform (LIT) method [1], using J-matrix inverse scattering potentials (JISP) [2,3]. The results are compared with those obtained with traditional realistic potentials, also including three-nucleon forces, and with the Unitary Correlation Operator Method potential (UCOM) of Ref. [4]. The aim is to investigate the underlying degrees of freedom of those potentials which reproduce the binding energies of light systems without the need of a three-nucleon force.
