Charged particle spectra from capture on Al

A. Gaponenko, A. Grossheim, A. Hillairet +3

Published data on the emission of charged particles following nuclear muon capture are extremely limited. In addition to its interest as a probe of the nuclear response, these data…

Decay of negative muons bound in Al

A. Grossheim, R. Bayes, J. F. Bueno +25

We present the first measurement of the energy spectrum up to 70 MeV of electrons from the decay of negative muons after they become bound in Al atoms. The data were taken w…

Using Thin Film Targets for Muonic Atoms and Muon Catalyzed Fusion Studies

TRIUMF Munoic Hydrogen Collaboration, M. C. Fujiwara, A. Adamczak +18

Studies of muonic atoms and muon catalyzed fusion have been conventionally done in a bulk target of gas, liquid or solid hydrogen isotopes. The use of thin film targets developed a…
