B. Lauss et al., EXPERIMENTAL-OBSERVATION OF EXCITED-STATE MUON TRANSFER IN MIXTURES OF HYDROGEN ISOTOPES, Hyperfine interactions, 102, 1996, pp. 285-291
The first direct measurement of q(1s) and its dependence on target den
sity and deuterium concentration was performed in HID (protium/deuteri
um) mixtures. Charge coupled devices (CCDs) were employed to detect th
e muonic hydrogen X rays. The presented preliminary results were obtai
ned by determining the relative K alpha-yields of both isotopes.
