Begum, Sakina (1972) Scattering of protons from helium. Doctoral thesis, Durham University.
The main work described in this thesis, is the original calculation of the excitation of helium by proton and of electron - capture process from helium by proton where the 2nd order potential introduced by Bransden & Coleman (1972)has been applied. It begins with a discussion of the existing methods relevant to the present work and followed by the construction of a second - order potential. A critical survey of the previous work has also been presented and its relation to the present work and result is discussed. The cross-sections for the following processes is calculated in the energy - range indicated (i) p + He(1S(^2)) →H(^+)(lS,2S,2p) + He(lS(^2)) 25 Kev - 500 Kev (ii) p + He(lS(^2))→H (IS) + He(^+)(IS) 30 Kev - 10 Mev The calculated cross - section along with existing results has also been presented and it is seen that the present method provides better results for the excitation process, but for the charge - exchange process, our results do not agree with the results of the experiment at high energies.
