The collisional metastability of antiprotonic atomcules He + — p in pure helium is discussed in the framework of a classical trajectory approach for three slow nuclei (αp — a) moving in an ab initio Born-Oppenheimer electronic potential. Our results support the destruction of the n > 41 states during the thermalisation stage, as well as the strong depopulation of the elliptic states adjacent to Auger-dominated short-lived levels.
