MONTE CARLO CALCULATIONS OF CROSS SECTIONS OF ELECTRON-POSITIVE MOLECULAR ION DISSOCIATIVE RECOMBINATION.
Abstract
In a recent paper, Bauer and Wu proposed a self-consistent model for the application of perturbation theory to calculating the general order of magnitude of cross sections of electron-positive molecular ion dissociative recombination. In applying their model to the calculation on a hypothetical system of electron capture by molecular hydrogen ions, it was necessary to make several approximations, without which it would have been exceedingly difficult to evaluate certain matrix elements. It is shown that Monte Carlo methods can be used for evaluating these matrix elements without restoring to approximations other than the model itself. The Monte Carlo method of stratified sampling has been tested successfully on the capture of electrons by molecular hydrogen ions. The dissociative recombination coefficient is found to be of the order of 3 x 10 to the -8th power cu cm/sec at room temperature, which is in agreement with reported experimental results. (Author)
