  In this work we review the classical recipe for estimating partial cross
sections for electron capture into selected energy levels within the Classical
Trajectory Monte Carlo (CTMC) method [R.L. Becker and A.D. MacKellar, J. Phys.
B: At. Mol. Phys. 17 (1984) 3923], and point to a deficiency of the method when
applied to the CTMC in its r-version, according to the terminology introduced
by Cohen [J.S. Cohen, J. Phys. B: At. Mol. Phys. 18 (1985) 1759]. We suggest,
in this case, an alternative recipe based on the generation of stationary
classical spatial distributions for electrons in arbitrary levels. The output
of the CTMC simulations is projected onto these classical distributions rather
than on the quantal ones. A comparison between the two approaches is done.
