A. Raeker et al., CHARGE CLOUD DISTRIBUTION OF HEAVY-ATOMS AFTER EXCITATION BY POLARIZED ELECTRONS, Journal of physics. B, Atomic molecular and optical physics, 26(8), 1993, pp. 1491-1508
We consider the charge cloud distribution of heavy atoms after impact
excitation by polarized electrons. A general formula in terms of state
multipoles is derived and interpreted with regard to ratios of princi
pal axes and three independent angles of rotation. Finally, the theory
is illustrated by numerical results for excitation of mercury and tha
llium.
