Abstract
For the processes mentioned in the title, the general rearrangement formalism of a previous paper is applied with specific consideration to the effect of molecule orientation on the electronic matrix elements and on the total and differential cross sections. Formulas are given for two cases: when one can and when one cannot treat the effect of rotation as a semiclassical orientation average. A short discussion is given of selection rules and of the use of these formulas in (a) ab initio calculation of the cross section, (b) approximate prediction of angular dependence, and (c) parametrization of experimental data.
