Abstract
The transverse polarization of electrons emitted in the decay of polarized nuclei has been measured. For the time-reversal violating triple correlation parameter we find . This result is in agreement with the standard model and yields improved constraints on exotic tensor contributions to the weak interaction. Combined with other experimental results and using a model for the coupling constants, a new limit for the mass of a possible scalar leptoquark, (90% C.L.), is obtained.
