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 ...
Study of angular correlation parameters using a distorted wave model
(Kenyatta University, 2004)
We have used a distorted wave model suggested by Singh in calculating the angular correlation parameters f... and R for electron-hydrogen collision. In this model the initial state distorted wave is generated by the ...
