GENERALIZED TABLES FOR THE CALCULATION OF DIPOLE TRANSITION PROBABILITIES IN LS - COUPLING,
Abstract
Calculation of transition probabilities or oscillator strengths for allowed trasitions proceeds in two steps: calculation of the dipolemoment matrix in a simple coupling scheme (usually LS-coupling) followed by transformation of this matrix to the energy scheme. Though the oscillator strength for and transition is proportional to the square of a matrix element, the transformation step requires absolute values, including signs (=). Existing tables of line and multiplet strengths omit these signs, and hence are useful only when the atomic states are nearly LS-coupling states - ofter a poor approximation. (Author)
