The J-matrix inverse scattering nucleon-nucleon potentials (JISP), describingboth two-nucleon data and bound and resonant states of light nuclei to highaccuracy, are tested on the total photoabsorption cross sections of Deuteron,Triton, 3He and 4He. The calculations in the three- and four-body systems arecarried out via the Lorentz integral transform method and the hypersphericalharmonics (HH) technique. To this end the HH formalism has been adapted toaccommodate non-local potentials. The cross sections calculated with the JISPare compared to those obtained with more traditional realistic interactions,which include two- and three-nucleon forces. While the results of the two kindsof potential models do not differ significantly at lower energies, beyond theresonance peak they show fairly large discrepancies, which increase with thenuclear mass. We argue that these discrepancies may be due to a probablyincorrect long range behavior of the JISP, since the one pion exchange is notmanifestly implemented there.Comment: 18 pages, 4 figures, 1 tabl
