Summary

We discuss the probability of semi-Pontecorvo reaction\(\overline p ^3 He \to \pi ^ - pp\) at rest and relate it to the admixture of 6q-bag in3He. According to our estimation, we find a branching ratio\(B(\overline p ^3 He \to \pi ^ - pp) \approx (1 \div 4) \cdot 10^{ - 5} \), for stopped antiprotons.
