Calculations of Planar-Channeling Effects on Rutherford Scattering in Single Crystals

The backscattering yields for planar channeling as a function of crystal orientation have been calculated using a temperature-dependent average potential. Temperature dependence of minimum yields ${\chi }_m$ and widths ${\psi }_{\frac{1}{2}}$ of the dips are studied and compared with experimental values obtained by different authors. An attempted calculation including nuclear multiple scattering is made.
