Abstract:
Thick gold single crystals of high quality were prepared for
Rutherford Backscattering Dechanneling studies by electropolishing and
annealing. The variation.; with temperature of the Random Fraction
versus Depth spectrtnn for 2 MeV He+ on < 110> gold was extracted from
measured Aligned and Random (Energy) Spectra. The measured dechanneling
rate showed a sixfold increase in going from 4loK to 293°K and is in
reasonable agreement with calculations made using the Steady Increase in
Transverse Energy (SITE) approximation.
