Abstract

Ion scattering spectra have been obtained for planar and near-planar channeling of He+ in germanium. Strong yield oscillations are observed in the energy spectra of the backscattered ions. The wavelength and stopping power of the incident ions have been determined from measurements of the energy separation between yield oscillations from spectra taken with various entrance and exit angles. The angle of inclination of the beam direction to the planes that produces the maximum scattering yield was also measured. This allowed the determination of the wavelength and stopping power by a second method. The wavelengths and angles for maximum scattering yields also provide information about the strength of the interaction potential between the ions and the target atoms.
