While advances in the understand-ing of p¯ collisions with the simplest one- and two-electron atoms, H and He, havebeen achieved experiment and theory did not agree for low-energy p¯ + He colli-sions (<40keV), stimulating a vivid theoretical activity. On the other hand, onlyvery few theoretical p¯ studies can be found considering molecular as well as otheratomic targets, in contrast to proton (p) collisions. This is in particular true for p¯impacts on H despite its fundamental role in representing the simplest two-electron2molecule. The obtained results may be useful for the p¯experiments at CERN (e.g.
