Calculations of the Cross-Section of Neutral Atoms and Positive and Negative Ions Towards the Absorption of Radiation in the Continuum

Abstract

The use of quantum mechanics in the calculation of the cross-sections of neutral atoms and of positive and negative ions towards the absorption radiation in the continuum is reviewed with particular reference to the practical difficulties and limitations on the accuracy obtainable. The general types of results to be expected are discussed. The detailed calculations that have already been carried out are summarized and the possibilities of future work are indicated.
