Nm. Kabachnik et al., IMPACT PARAMETER DEPENDENCE OF ENERGY-LOSS STRAGGLING IN ION-ATOM COLLISIONS, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 83(4), 1993, pp. 591-593
The impact parameter dependence of the straggling in electronic energy
loss of fast protons in collisions with many-electron atoms is calcul
ated within the semiclassical approximation and the independent electr
on model with Hartree-Slater potential. The results for p+Ar collision
s are in very good agreement with recent experimental data by Auth and
Winter [Phys. Lett. A 176 (1993) 109].
