Comment on "Degenerate Wannier Theory for Multiple Ionization"
M. Yu. Kuchiev, V. N. Ostrovsky
Abstract
Recent Letter of T.Pattard and J.M.Rost (Phys.Rev.Lett 80, 5081 (1998)) suggests that there exist logarithmic corrections to the near threshold cross section for the processes of break up of a particle into several charged fragments. This comment shows that it is incorrect, the logarithmic terms never exist. The cross section for all processes behaves as some power of the above-threshold energy, similarly to the known Wannier problem.
