A METHOD OF DETERMINING THE ELECTRONIC TRANSITION MOMENT FOR DIATOMIC MOLECULES
A method is described that will give the variation, as a function of internuclear distance, of the electronic transition moment governing intensities in diatomic molecular band systems. ReliableExpand

S-wave positron scattering by hydrogen atoms
The S-wave scattering of positrons by hydrogen atoms is studied using the coupled static approximation with 26 correlation functions for energies up to the excitation threshold of hydrogen. Up to aExpand

EFFECTS OF VIRTUAL EXCITATION OF THE 2s STATE ON THE ELASTIC SCATTERING OF ELECTRONS BY ATOMIC HYDROGEN
The elastic scattering of electrons by hydrogen atoms, for electron energies below the first threshold of excitation of the atom (10.2 ev), is investigated numerically making full allowance forExpand

Transition probability parameters of molecular spectra arising from combustion processes
Abstract The dependence of intensity distributions in molecular spectra upon ( a ) source conditions and (b) molecular constants (particularly transition probabilities) is discussed briefly.Expand
