Kh. Besch et al., STRUCTURE OF THE TRIPLY DIFFERENTIAL CROSS-SECTION IN THE RECOIL REGION IN RELATIVISTIC ELECTRON-IMPACT IONIZATION .1. EXPERIMENT, Journal of physics. B, Atomic molecular and optical physics, 30(2), 1997, pp. 73-75
We report here on an (e, 2e) measurement at relativistic electron ener
gy (300 keV) on the K shell of copper (E(bind) = 9 keV). Using coplana
r asymmetric kinematics the angular distribution of the relative tripl
y differential cross section was measured and is compared with a calcu
lation using relativistic distorted-wave Born approximation. We find a
distinct structure in the recoil region which is in reasonable agreem
ent with the theoretical data.
