ON A COHERENT NON-LOCAL SEPARABLE N-N INTERACTION

Publisher Summary The simplification introduced in the three-body problem by the use of nonlocal separable interactions (NLSI) has focused the interest of many physicists on this kind of potential. Several attempts have, thus, been done to define NLSI leading to a correct description of the N-N elastic scattering phase shifts. When NLSI are used, the two-term potentials are indispensable to yield a correct description of the N-N phase shifts. The NLSI is directed to give a correct fit of the N-N elastic scattering phase shifts. The additional requirements are imposed to give a correct description of deuteron and of low energy parameters. NLSI gives a correct answer to several different nuclear properties.
