Abstract
The creation of muon pairs by (anti)neutrinos in the Coulomb field of the nucleus provides a direct test of the interference between the intermediate-vector-boson amplitudes, as predicted by the weak-interaction theory. This paper summarizes the main features of the above process and discusses the feasibility of measuring the W-Z interference by searching for recoilless dimuon events using fine-grained counter neutrino detectors. The result from an earlier experiment which searched for this process is discussed in the context of the present calculation.
