Abstract The ion-clustering mechanism of the quenching of the metastable 2S-state of the muonic helium ion (μHe) 2S + in gaseous helium is studied on the basis of quantum-chemical calculations of clusters He n (μHe)+. It is shown that the quenching rates do not depend on the cluster ordern atn ≥ 2. In the helium gas at the pressure 0.1 ≲p(atm) ≲ 10 the quenching of (μHe) 2S + proceeds, mainly, at the vibrationally excited levels of He(μHe) 2S + cluster, while atp ≳ 10 atm, at the ground vibrational state of the cluster He2(μHe) 2S + . Atp ≥0.1 atm the calculated quenching rates agree with the recent experimental data.
