As noted by Martin and Glauber , the polarization of the photon in S-state
orbital electron capture is also sensitive to the phase of the vector and axial-vector couplings in the low-energy interaction Hamiltonian  if the anti-neutrino is no longer assumed to be strictly right-handed.
Starting with magnetization in a specified zero-field "s-state
," fields are applied instantaneously to reverse the magnetization, and the evolution of the magnetization is traced as the magnetization comes to equilibrium in its new state.
