- Abstract
- Rutherford backscattering at two different angles on multilayer targets is used to measure the stopping cross sections of helium in four amorphous hydrogenated silicon carbide compounds (a-SixC1-x:H) in the energy range from 200 keV to 1600 keV. The measured stopping cross sections are compared to the values calculated by means of Bragg's rule. It is found that C-H and Si-C chemical bonding effects limit the validity of this additivity law whereas the influence of Si-H bonds is small in these ternary compounds.
