Semi-empirical model MQDT calculation of odd parity, J = 3 autoionizing states of barium

We have constructed MQDT parameters for the odd parity, J = 3 autoionizing states of barium by using single configuration wavefunctions to calculate Slater integrals, and transforming them into an MQDT R matrix. We then compared our values with the measured branching ratios for autoionization into the 5d{sub 3/2} ion channels to modify the calculated values. For states converging on the lower, 6p{sub 1/2} ion limit, the branching ratios have a complex dependence on energy, so that a curve fitting process has considerably more reliability than one which just uses the resonance energy values. This provides a convenient way to characterize the complex spectra and branching ratios for multi-electron atoms.
