Abstract
The excitation n=1 to n=2 interval probability function for e-H collisions has been examined using a classical model. The electron-hydrogen atom long range interaction has been accounted for via a static dipole potential of the atom, and electron motion in the atomic dipole field has been examined analytically. The results obtained are used for initiations of numerical calculations in the close interaction region. A three body classical computer program by Abrines et al. (1966) has been used for the numerical calculations. The initial atomic orientation interval function per unit final energy band of the atom, for the total angular momentum L=1.665 au (plane case) has been evaluated in the energy range: 0.378<or=E (au)<or=0.411. The function obtained shows an oscillatory behaviour with two maxima at approximately 0.381 and 0.390 au. A comparison with existing experimental data and quantum mechanical results is made.This publication has 16 references indexed in Scilit:
