The measurement, performed at TRIUMF, used a high purity liquid deuterium target. The energy measurement was based on the time-of-flight technique which relied on detecting both neutrons present in the final state within a constrained geometry. The final spectrum obtained shows evidence of a possible en­hancement of the neutron yield in the 35-50 Mev energy range. The find­ings are consistent with the prediction for the high energy neutron limit of a 200% enhancement due to meson exchange currents. The results show that further experimental investigation of light nuclei ( A ~ 4) is neces­sary to determine whether meson exchange currents are responsible for the observed enhancements in the energetic particle spectrum following muon capture in heavier nuclei.94 pagesAvailable to the World Wide WebThesis
