One of the important tools for the solution of a few-body Schrödinger equation is the hyperspherical harmonics expansion method. Ever since its inception, the method has been used extensively in atomic and molecular problems. However, this method when used with some realistic potentials like Reid soft core leads to a very complicated numerical procedure even for the trinucleon system. This paper discusses a new method for the evaluation of matrix elements in such cases. This is demonstrated with numerical evaluation of a few typical matrix elements.
