摘要
In this work, the binding energy and wavefunctions of three-nucleon systems are obtained by using hy-perspherical harmonic approach. We have used a mathematical modification method to obtain the eigenvalues and eigenfunctions of Schrdinger equation for three-nucleon systems in calculation. Next, we have used a simple approach to obtain the difference between binding energy of 3H and 3He where gives us mass splitting of three-nucleon systems. We have compared our results with the other works and experimental values.
