  • Abstract
    In this method, the coefficients of the vector addition theory are obtained by relating them to that of the scalar addition theorem for which an efficient recurrence relation has been derived by Chew (1992). This new scheme of calculating the coefficients is of reduced computational complexity. Hence, when the number of coefficients required is large, the present methods are many times faster than the traditional method using Gaunt coefficients and Wigner 3j symbols.<>
