摘要

The effective operator A(Gamma) for the Auger l(1)(N1)l(2)(N2)-> l(1)(N1+1)l(2)(N2-2)epsilon l(3) transitions was determined in the nonrelativistic approximation in the second quantization representation in the case of normal ordering of electron creation and annihilation operators. The matrix element of A 0 yields a partial Auger width of a level. The specific transitions when l(2) = 1, 2 and l(1) > 0 were considered in detail. The general formula for a matrix element of A 0 was derived when a wavefunction with open-shells was presented in normal coupling. Compact expressions for the matrix elements of A(Gamma) in the case l(1)(N1)l(2)(2) when N-1 = 1, 2, 4l(1) + 1 and 4l(1) were obtained. The selection rules for matrix elements of A(Gamma) are discussed by using the quasispin technique.
