Abstract

At the RIKEN-RAL Muon Facility, we have observed K(β) (3p → 1s) μα sticking X-rays from muon catalyzed D-T fusion with various tritium concentrations (C(t) = 0.1 - 0.7) and high density solid and liquid phases. Statistics of K(β) X-rays were not enough to determine the peak shape, but the intensity was obtained with an adequate constraint to the K(β) shape using the theoretically calculated peak shape. No significant dependence of the K(β)/K(α) ratio on these target conditions was found, and our results (Y(K(β))/Y(K(α)) ~ 7%) gave smaller values than the existing theoretical calculations. It suggests an existence of unexplained atomic process in the collision processes between (αμ)+ and condensed media. (C) 2000 Published by Elsevier Science B.V.
