Impact Parameter Dependence of K-Shell Ionisation by Relativistic Ions

摘要

The semiclassical approximation is extended to the case of ionisation of atoms by relativistic charged particles. The theory is formulated both for a relativistic and a non-relativistic electron description. For total cross-sections the theory is shown to be equivalent to the relativistic plane wave Born approximation. Numerical results for the impact parameter distribution of the ionisation probability for the K-shell are given. (Atomindex citation 12:617458)
