Abstract

Authors investigated the dechanneling properties of 5 MeV protons in left brace 110 right brace planes in silicon. From measurements of the spectra of particles transmitted through a 60 mu thick crystal the half-thickness (x one-half ) for dechanneling is deduced for crystal temperatures between room temperature and 600 C. An absence of a significant temperature dependence of multiple scattering in the plane is observed and suggests that the multiple scattering is predominantly electronic. Calculations of the dechannelling length, x// one-half as a function of temperature, using the Monte-Carlo critical angle results of Barrett, are found to agree very well with the experimental results.
