Abstract

• The purpose of this research is to study the resonance energy of He (, n) system by solving the two body Schrdinger equation with complex scaling method. The Gaussian basis wave function is used to solve the two body Schrdinger equation for (J = 3/2- ) state and (J = 1/2- ) state in spin-orbit coupling. The calculated resonance energies and level widths for (J = 3/2- ) state and (J = 1/2- ) state are (0.747, 0.596) MeV and (2.147, 5.533) MeV respectively. Comparison is made with the experimental data and good agreement is found
