Light-ion neutralization behavior in the 25 to 150 keV range using a medium-energy ion-reflection spectrometer

Charged fractions of H, D, He, Li, B, C, N, F and Ne backscattered from Au surfaces have been measured. These backscattered particles with energies in the range 25 to 150 keV are counted and energy analyzed by a high resolution solid state detector. The charged fractions of H and He appear to almost follow a simple dependence on the emergence velocity. This is, however, not true for heavier ions. Li shows the highest charged fraction followed …
