Five trivial pages of an extremely trivial extension (viz., from
three to D dimensions) of an old and trivial use of the exponential
approximation (7) of the centrifugal term in the radial Schroedinger
equation in Refs. [26] and [27]. The idea is traceable back to the
book [14] of elementary exercises but its carboncopying proves,
alas, unbelievably productive in our ``publish or perish"
contemporary world controlled by increasingly irresponsible
referees.
