Energy- and angle-differential yields of electron emission from thin carbon foils after fast proton impact

Abstract

Proton-induced electron emission from sputter-cleaned thin carbon targets was investigated under ultrahigh vacuum conditions using time-of-flight energy analysis. These data emphasized the low-energy portion, e.g., ${\mathit{E}}_{\mathit{e}}$20 eV, of the spectrum. Energy distributions of the emitted electrons were measured as a function of the emission angle, impact energy, and foil thickness. \textcopyright{} 1996 The American Physical Society.
