Abstract
Spectra of energetic protons and deuterons emitted following negative muon capture from rest in have been measured for the first time. Significant capture strength is observed at high energy transfers (->60 MeV) for the two-body and three-body breakup channels, indicative of the importance of nucleon-nucleon correlations and meson exchange currents in the capture process. A simple plane wave impulse approximation calculation reproduces the proton spectrum reasonably well, but underpredicts the deuteron rate at the highest energies by a large factor.
