A. Volnykh, V. P. Woźniak, J. 2004-01-29 The paper describes an experiment aimed at studying muon capture by He nuclei in pure ³He and D₂+³He mixtures at various densities. Energy distributions of protons and deuterons produced via µ₋+³He-->p + n + n + νµ and µ₋+³He-->d + n + νµ are measured for the energy intervals 10–49 MeV and 13–31 MeV, respectively. Muon capture rates lambda_cap^p(ΔEp) and lambda_cap^d(ΔEd) are obtained using two different analysis methods. The least-squares methods give lambda_cap^p = (36.7±1.2) s–1, lambda_cap^d = (21.3±1.6) s–1. The Bayes theorem gives lambda_cap^p = (36.8±0.8) s–1, lambda_cap^d = (21.9±0.6) s–1. The experimental differential capture rates, dlambda_cap^p(Ep)/dEp and dlambda_cap^d(Ed)/dEd, are compared with theoretical calculations performed using the plane-wave impulse approximation with the realistic nearest-neighbor interaction Bonn B potential. Extrapolation to the full energy range yields total proton and deuteron capture rates in good agreement with former results application/pdf https://folia.unifr.ch/global/documents/299822 https://folia.unifr.ch/documents/299822/files/1_schaller_mch.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevA.69.012712 info:eu-repo/semantics/openAccess License undefined Physical Review A. - 2004, vol. 69, p. 012712-12727 info:eu-repo/classification/udc/53 Muon capture by ³He nuclei followed by proton and deuteron production http://purl.org/coar/resource_type/c_6501
