    "abstract": "We report the first direct observation of excited state muon transfer in\nhydrogen/deuterium mixtures by direct measurement of q_1s, the probability that\na mu-p atom, which is initially formed in an excited state, reaches the 1s\nground state. The dependence of q_1s on deuterium concentration c_d was\nmeasured for two different densities at cryogenic temperatures using charge\ncoupled devices (CCDs) to detect the muonic X rays. First results based on the\nanalysis of the K_alpha-lines of the two isotopes are presented.",
