Computer simulation of the grazing incidence backscattering of protons from a (110) nickel surface. [Energy and angular distributions, 01 to 5 keV]

OSTI ID:7077204
The computer program MARLOWE was used to study the processes whereby protons are reflected from the (110) surface of a nickel crystal. The ions were incident in the (001) plane, at an angle of 7.5 degrees from the surface. Energy and angular distributions of the backscattered particles were investigated for the incident energy range 0.1 to 5 keV. The results were compared with similar ones for an amorphous target. Total reflection of the beam occurred below 1.2 keV. Focusing in the (110) semichannels was found to be energy dependent and to be strongest under total reflection conditions. The energy distributions of the reflected particles showed a complex structure which is dependent on the incident energy. This structure is interpreted in terms of detailed reflection mechanisms.
