|Title:||Application of the method of continued fractions to multichannel studies on electronic excitation of H-2 by electron impact|
|Abstract:||In the present work, the method of continued fractions at a five-channel close-coupling level of approximation is applied to study the low-energy electron-impact excitation in linear molecules. Particularly, cross sections for the X(1)Sigma (+)(g)-->b(3)Sigma (+)(u), X(1)Sigma (+)(g)-->a(3)Sigma (+)(g),and X(1)Sigma (+)(g)-->c(3)Pi (u) transitions in H-2 in the (15-40)-eV energy range are reported. As in our early two-state studies, no orthogonality constraint between the bound and continuum orbitals is imposed and the one-electron exchange terms are considered explicitly. In general, our calculated cross sections are in good agreement with the results obtained by the four-state Kohn variational method. Comparison between our calculated results with available experimental data is encouraging.|
