The effective operator for the Auger l1N1l2N2l3N3→l1N1+1l2N2-1l3N3-1εl4 transitions

The effective operator for the Auger l1N1l2N2l3N3→l1N1+1l2N2-1l3N3-1εl4 transitions is considered in the second quantization representation in the nonrelativistic approximation. The quasispin technique is used for analysis of the effective operator. Compact expressions of the Auger width for specific li and Ni are presented.
