Ion beam analysis of ZnSe

The Rutherford Backscattering Spectroscopy (RBS) spectra of Li-doped ZnSe ([Li]≥1018 cm-3) are measured with a He+ ion beam at 2.0 MeV. The backscattering yield for aligned incidence increases with increases in Li concentration. Nuclear reaction analysis of 7Li(p, n)7Be is performed. The angular dependence of the neutron yield around and incidence directions suggests that the lattice site of Li is displaced from the ordinary lattice sites of the ZnSe lattice.
