Sn. Nakamura et al., Measurement of the K-beta/K-alpha ratio for muon alpha sticking X-rays in muon catalyzed d-t fusion at the RIKEN-RAL Muon Facility, HYPER INTER, 118(1-4), 1999, pp. 209-212
At the RIKEN-RAL Muon Facility, mu(-) to alpha sticking K-beta X-rays were
observed for the first time taking advantage of the pulsed beam structure.
The precision of the present measurements was insufficient to distinguish b
etween theoretical models, however the observed K-beta/K-alpha X-ray intens
ity ratio tends to be smaller than most of these theoretical predictions.
