Abstract

The yield of first-surface secondary electrons from H+ impact on aluminum and gold targets is measured. Data are obtained for proton energies of 5 ≤ E ≤ 24 MeV on aluminum and 5 ≤ E ≤ 18 MeV on gold, and these data are compared with theoretical expectations and with previous data for lower proton energies. An empirical curve for the yield from aluminum-oxide is obtained from a theoretical curve for pure aluminum by using earlier measurements of primary-electron-produced yields from both aluminum and aluminum-oxide.
