Multiparameter coincidence experiments to investigate desorptionmechanisms with heavy ions of Kr, Ag, U in the energy range of 0.1 MeV/u TO 5 MeV/u

Abstract

Experiments with heavy ion beams from accelerators have been performed to study the desorption of atomic and secondary ions. The shapes of the yield curves have been measured for energies of projectiles ranging from O.1 to about 5 MeV/u. Secondary electron yields have been measured in coïncidence with projectiles and secondary ions. A Different primary ion velocity dependence is found for electron and secondary ion yields.
