Measurement of the Transverse Polarization of Electrons Emitted in Free-Neutron Decay
Measurement of the Transverse Polarization of Electrons Emitted in Free-Neutron Decay
Both components of the transverse polarization of electrons (sigmaT1, sigmaT2) emitted in the beta-decay of polarized, free neutrons have been measured. The T-odd, P-odd correlation coefficient quantifying sigmaT2, perpendicular to the neutron polarization and electron momentum, was found to be R=0.008+/-0.015+/-0.005. This value is consistent with time reversal invariance and …
