Abstract An independent alternative calculation is performed for narrow near-threshold resonances in the e+–He+ system using the stabilization method in the framework of hyperspherical coordinates (HSSM). A narrow resonance at Er=−0.249995 with width Γ=1.9×10−5, associated with the He2+–Ps (n =1) threshold is confirmed. The resonances around the energies −0.365 and −0.195, predicted by Bhatia and Drachman [Phys. Rev. A 42 (1990) 5117] and confirmed by Ho [Phys. Rev. A 53 (1996) 3165], do not appear in our calculations.
