Electron Impact Excitation of 2 1S State of Helium Atom
(Faculty of Science Kenyatta University, 2005)
We have applied a distorted wave method to calculate the differential cross sections for 2 1S excitation of helium atom by electron impact in the energy range of 50-200 eV. The results are compared with some other ...
A generalized Coulomb-projected Born Calculation using Screened Coulomb Potential
(Faculty of Science Kenyatta University, 1998)
The Coulomb-projected Born method proposed by Geltman has been generalized by using the screened Coulomb potential of the form in place of the nuclear potential experienced by the incident electron. The results obtained ...
