When muons are captured by protons in the process muon - p to n neutrino there exists a correlation between the momentum of the neutron and the spin of the muon. With a polarized muon beam, this correlation establishes a spatial asymmetry in the direction of emission of the neutron relative to the direction of muon polarization. An experiment designed to measure this asymmetry was performed at the Nevis Laboratory of Columbia University. A pure muon beam from the Nevis synchrocyclotron was stopped in Ca40 and C12 targets located in a uniform transverse magnetic field. The resulting uniform precession of the muon spin transforms the spatial asymmetry to a time interval distribution as recorded by a fixed detector.
