EMERGING CHARGE STATE AFTER GRAZING COLLISIONS OF IONS ON SnTe SURFACES C.C. Montanari, M.S.Gravielle$^\ast$ and J.E. Miraglia Instituto de Astronomia y Fisica del Espacio, C.C. 67, Suc. 28, 1428 Buenos Aires, Argentina $^\ast$Also at Departamento de Fisica, FCEyN, Universidad de Buenos Aires Emerging charge states for ions impinging grazingly on a SnTe surface are calculated at high impact velocities. The charge state distribution is obtained as result of electron capture and loss processes produced by binary collisions of the projectile with the surface atoms. We find that the projectile comes out of the surface with a charge state larger than that corresponding to transmission through solids.
