Elastic Resonance Scattering Study of Protons on Aluminium

Abstract

Proton Elastic Scattering Cross sections have been measured in this thesis for aluminium. The data was collected at two laboratory angles of 1400 and 1700. The energy range given was from 1 to 3 MeV in small steps of 0:01 MeV. The aluminium targets were prepared by the deposition of pure aluminium on gold and silver foils which served as backing material. The deposition techniques in- cluded Sputtering and Electron Beam Evaporation. The thickness of the coated aluminium target was measured by the resonator of Electron Beam Evaporation System and was about 200 nm. The proton beam used was produced by SNICS-II source and made available by NCP Tandem Accelerator Laboratory, Islamabad. The Non-Rutherford cross sections have been calculated and plotted for both an- gles. The ratio of Non-Rutherford to Rutherford cross sections have also been calculated and plotted for the same two angles. The results were compared with three past papers of similar calculations and were in qualitative agreement with them.
