| Abstract: | A new simple graphical method of the unitary group subduction coefficients has been considered.In combination with the Weyl graphical method of the U(n)generator matrix elements, which we recently presented, the evaluation of the U(n)generator matrix elements in the non-canonical basis symmetry adapted to the Subgroup chain U(n=n_1+n_2)??U(n_2)??U(n_2)can be determinated, which appears in the shell-model approach in atomic and molecular systems. |
