Both components of the transverse electron polarization have been measured in free neutron decay. The T-odd, P-odd correlation coefficient associated with polarization component perpendicular to the neutron polarization and electron momentum, was found to be R = 0.006 +/- 0.012 +/- 0.005. This value is consistent with time reversal invariance, and significantly improves limits on the relative strength of imaginary scalar couplings in the weak interaction. The value obtained for the T-even, P-even correlation coefficient connected with the second transversal polarization component, N = 0.065 +/- 0.012 +/- 0.004, agrees with the Standard Model expectation providing an important sensitivity test of the experimental setup.
