| ABSTRACT: |
Recently，Esry and Sadeghpour (2003)，and Hesse, Le and Lin (2004)，have reported calculations of protonium formation in
\bar{p} + H
collisions at low energies, using hyperspherical coordinates in a hyperradial adiabatic approach. In order to make the problem tractable both groups were forced to introduce an artificial proton mass
m'_p＝17.824a.u.
and
m'_p＝100a.u.,
respectively，which raises doubts as to the physical relevance of their results and conclusions. Here we make use of the hyperspheroidal coordinates in a hope to attack the same problem in basically the same approach but without need for changing the physical particle masses. |
