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

This contribution reports on a recent calculation of the total photonuclear cross sections of 2H, 3H, 3He and 4He performed with the Lorentz Integral Transform (LIT) method [V.D. Efros, W. Leidemann, and G. Orlandini, Phys. Lett. B 338 (1994) 130], using J-matrix inverse scattering potentials (JISP) [A.M. Shirokov et al., Phys. Lett. B 68 (2003) 041001(R); A.M. Shirokov, J.P. Vary, A.I. Mazur, T.A. Weber, ArXiv.org:nucl-th/0512105]. 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. [R. Roth, T. Neff, H. Hergert and H. Feldmeier, Nucl. Phys. A 745 (2004) 3]. 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.
