We report the first direct observation of excited state muon transfer in hydrogen/deuterium
mixtures by direct measurement of q 1 s, the probability that a μ p atom, which is initially
formed in an excited state, reaches the 1 s ground state. The dependence of q 1 s on
deuterium concentration cd was measured for two different densities at cryogenic
temperatures using charge coupled devices to detect the muonic x rays. First results based
on the analysis of the K α lines of the two isotopes are presented.
Abstract
We report the first direct observation of excited state muon transfer in hydrogen/deuterium mixtures by direct measurement of q 1 s, the probability that a μ p atom, which is initially formed in an excited state, reaches the 1 s ground state. The dependence of q 1 s on deuterium concentration c d was measured for two different densities at cryogenic temperatures using charge coupled devices to detect the muonic x rays. First results based on the analysis of the K α lines of the two isotopes are presented.
