Differential electron-ion elastic scattering cross sections extracted from ion-atom collisions of 0.53 MeV/u Cu⁵⁺on H₂

Electron-ion scattering

“…Further studies of this kind have included the observation of binary encounter electrons at angles other than 0 • in the laboratory, corresponding to electrons backscattered through a range of angles in the centre-of-mass frame of reference. The derived backscattering results of Liao et al (1997a) for Cu 5+ ions are shown in figure 19, where they are compared with a partial waves calculation after Bhalla and Shingal (1991). The experimentally derived features are seen to be in broad agreement with the theory, showing strong scattering near 180 • , falling to a minimum around 120 • .…”
