The (0 0 1) surface of Si is irradiated with 30 keV Ga + ions at various angles of incidence. The surface topography of the irradiated sample is observed with atomic force microscopy (AFM). While the roughness increases with fluence at angles of inci

Energy losses of 15–30 keV Ne + , Ar + and Kr + ions specularly reflected from a SnTe(0 0 1) surface are measured. Because more than 98% of the reflected ions are neutral, the observed energy loss can be considered as the result of atom–surface i

Secondary-electron yield induced by MeV protons specularly reflected from a SnTe(001) surface is measured. From the observed secondary-electron yield, the position-dependent secondary-electron production rate $P(x)$ is derived as a function of distan

Energy losses of 0.8 MeV/atom small B n ( n ≤ 4) clusters transmitted through thin carbon foils ranging from 2 to 16 μg cm −2 have been measured. The ratio of observed energy loss per atom of B n clusters to the energy loss of single B ions show

We have developed a high-resolution Rutherford backscattering spectroscopy (RBS) system with a 90°C sector magnetic spectrometer ( δE E ∼ 0.1% , including the energy spread of the incident beam). Energy spectra of sub-MeV He1 ions backscattered f

We have measured energy losses of 0.8-MeV/atom B n ( n ≤ 4) clusters transmitted through thin carbon foils (2–17 μg/cm 2 ). The ratio of observed energy loss per atom of B n clusters to the energy loss of isolated B ions is larger than unity at

The resonant coherent excitation (RCE) of surface planar channeled B4+ ions from n=1 to n=2 on a SnTe (0 0 1) surface is observed at various azimuthal angles through the reduction of the B4+ fraction which is caused by the ionization of the excited B

The (0 0 1) and (1 1 1) surfaces of PbTe have been observed by high-resolution Rutherford backscattering spectroscopy (HRBS) and reflection high-energy electron diffraction (RHEED). The observed HRBS spectra for the incidence of 300–350 keV He + io
