Machine computation of saturation parameters in a multilevel zeeman system

Abstract

The "inspection method" of Keating and Barker for the solution of the rate equations to determine the steady-state normalised population distribution in a multilevel system is modified to enable use of the explicit forms of various lattice-induced relaxation probabilities in an electron nuclear-coupled Zeeman system, and also to program the calculations for high speed digital computers. The various lattice-induced relaxation probabilities are taken as linear combinations of certain parameters, which characterize the various relaxation mechanisms in the Zeeman system. Using our procedure for the evaluation of the saturation parameters, the program is also capable of evaluating the saturation parameters both in the finite temperature and infinite temperature cases. As examples, results of calculations on six-level and ten-level spin systems are presented.
