Ortho-para conversion in the muonic molecule pp μ

Abstract

The ortho-para conversion due to the interaction between the nuclear magnetic moments and the atomic electron is considered in the muonic molecule (ppμ)e produced in the ortho state. It is shown that the rate of this transition is w≈0.466 s−1, which is much less than the rate of the transition induced by the mixing of states having opposite parities with respect to the inversion of the muon coordinates.
