A NEW APPROACH FOR CALCULATING THE MATRIX ELEMENTS OF UNITARY GROUP GENERATOR PRODUCTS
计算酉群生成元乘积矩阵元的一个新途径

In this paper we give a simple method by which all the Gelfand states can be obtained from the action of a generator on a Gelfand state. Combining with the method of calculating segment values, we suggest an approach to calculate the matrix elements of unitary group generator products.
