Comparison of analytic and Monte Carlo results in distant-pair recombination

In recent papers, Eggert [Phys. Rev. B 29, 6664 (1984) and 29, 6669 (1984)] has criticized analytic treatments of distant-pair recombination and has presented Monte Carlo solutions. Calculations of the photoluminescence decay curves and of the metastable population densities show that the Monte Carlo solutions agree remarkably well with the analytic predictions. Where the two methods give different results, the analytic solutions are physically more realistic.
