  Nuclear Hulthén potentials for F and G partial waves

  By Patitapaban Sahoo, Ashwini Kumar Behera, Bidhan Khirali, Ujjwal Laha

  Abstract: In the past few decades, several investigation have been made and at the same time a number of theoretical models have also been projected for the nucleon-nucleon scattering in the low and intermediate energy range. These phenomenological models involve large number of free parameters to be fitted to reproduce the physical observables. In contrast to these potentials a two-term four parameter nuclear Hulthén type interaction is proposed to describe the …

  Energy-Momentum Dependent Potentials and np Scattering

  By Ujjwal Laha, Ashwini Kumar Behera, Madhura Majumder, Jhasaketan Bhoi

  Abstract: Energy-dependent equivalent local potential corresponding to a rank 2 nonlocal interaction isconstructed for the partial wave   0 and the higher partial wave equivalent localinteractions are developed by exploiting the formalism of super symmetry formalism. Themerit of our constructed potentials is judged through a model calculation. Our results are ingood agreement with standard data.Keywords: Equivalent local potential, non-local potential, scattering phase shifts, super symmetry formalismCite this ArticleAshwini Kumar Behera, …
