Effective Range Approximation in Variable Phase Approach for Triplet \(^3S_1^{\{np\}}\) and Singlet \(^1S_0^{ \{nn, np, pp\}}\) State

This work is a short communication where phase function method has been applied to obtain the phase shifts using Effective Range Approximation potential for \(^3S_1-np\), \(^1S_0-nn\), \(^1S_0-np\), and \(^1S_0-pp\) states. No free fitting parameters are used in calculations and reasonably good matc...

Description
Summary:This work is a short communication where phase function method has been applied to obtain the phase shifts using Effective Range Approximation potential for \(^3S_1-np\), \(^1S_0-nn\), \(^1S_0-np\), and \(^1S_0-pp\) states. No free fitting parameters are used in calculations and reasonably good match with the experimental phase shifts is observed for E \(\leq\) 20 MeV. Potentials are obtained for n-n, n-p, and p-p scattering that are exponential well-shaped.
