Title: Low Energy p-bar+ H Collisions in Hyperspheroidal Coordinates

Abstract

Recently, Esry and Sadeghpour (2003), and Hesse, Le and Lin (2004), have reported calculations of protonium formation in p-bar+ 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{sub p}{sup '} = 17.824 a.u. and m{sub p}{sup '} = 100 a.u., respectively) which raises doubts as to the physical relevance of their results and conclusions. Here we make use of the hyperspheroidal coordinates in order to attack the same problem in basically the same approach but without need for changing the physical particle masses.
