C. Belenger et al., ELASTIC LARGE-ANGLE SCATTERING OF ELECTRONS BY MULTIPLY-CHARGED IONS, Journal of physics. B, Atomic molecular and optical physics, 29(19), 1996, pp. 4443-4456
Differential cross sections for the elastic scattering of electrons by
multiply charged ions have been measured at scattering angles between
32 degrees and 148 degrees. Mainly at backward angles the cross secti
on deviates remarkably from the Rutherford cross section showing oscil
lations due to the structure of the ionic core. Experimental results o
btained for Ar8+ ions and different Xe-q+ ions (3 less than or equal t
o q less than or equal to 6) are found to compare well with theoretica
l calculations.
