Abstract
The impact of excited state muon transfer in dµ + H2 collisions has been investigated. The formation of metastable pdμ* molecules and their subsequent decay into the pμ (1s) + d channel opens a transfer channel that is otherwise closed at the n=2 level. This mechanism enlarges the fraction of muons arriving to the ground state of the lighter isotope. The resulting ground state population P pμ1s as function of deuterium concentration appears to be in qualitative agreement with recent measurements of the K α X-ray yield in H2/D2 mixtures.
