Differential ionization studies at forward angles
Tóm tắt
The energy distribution of the scattered positron and electron projectiles following ionization of Ar have been measured around 0‡ and 100 eV impact energy. At 30‡ an estimate of the absolute double differential cross-section of both outgoing particles (electron and positron) was determined at 100 eV impact energy.
