Abstract
It has been shown that the helicity-dependent imaginary part of the weak neutron interaction does not preserve spatial parity and breaks T-invariance. Time reversal symmetry breaking also occurs with a strong spin dependent interaction. The group structure of the spinor transformation in both cases is related to the Lorentz group transformations.
