Radiative muon capture on oxygen and the induced pseudoscalar coupling

Academic Article


  • The photon spectrum from radiative muon capture in O16 has been measured using a time projection chamber as a large acceptance pair spectrometer. The integrated partial branching ratio for photons of E>57 MeV, relative to the ordinary muon capture rate, is (2.20.2)×10-5. When compared to a calculation using a phenomenological nuclear response function the data indicate a value for the induced pseudoscalar coupling in O16 of gp/ga=7.30.9; however, when compared to a microscopic nuclear-model calculation the value gp/ga=13.6-1.9+1.6 is obtained. © 1989 The American Physical Society.
