摘要
The allotropic effect on the electronic topping power of protons in solids was systematically determined by the nuclear resonance reaction ^(27)Al(p,γ)^(28)Si at E_(p)=774 and 992ke V in an silicon on sapphire(SOS)sample of epitaxial Si on sapphire.Details of the experimental technique are described.The experimental error is less than 3%.
