G. Ivanovski et al., CLASSICAL DESCRIPTION OF STATE-SELECTIVE TRANSITIONS IN COLLISIONS OFCHARGED-PARTICLES WITH ATOMS, Journal of physics. B, Atomic molecular and optical physics, 28(22), 1995, pp. 4799-4809
A classical description of state selective excitation processes in ato
m-charged particle collisions is provided for arbitrary values of the
collision energy. Closed-form expressions for the cross sections of nl
--> n', nl --> l' and nl --> n'l' transitions are obtained in the hig
h energy limit. The scaling properties of sigma(nl --> n'l') cross sec
tions are briefly discussed.
