Abstract

We calculate decay widths of the metastable ppμ^*_ν,J molecular ion in non-adiabatic approach. The muonic molecular ion can be formed in collision of the excited pμ(2s) atoms with H₂. Then, decay of the ppμ^*_ν,J system opens a path for the muon from pμ(2s) to pμ(1s). We employ trial wave function which includes non-adiabatic terms to calculate some radiationless decay widths. The present results of the widths do not good agree with those given in our previous work, while are more close to recent data of other researchers.
