Abstract
It is shown that the weak states which are used in the standard treatm ent of neutrino oscillations do not, in general, describe correctly th e neutrinos produced and detected in weak-interaction processes. It is also shown that it is impossible to construct a Fock space of weak st ates. However, neutrino oscillations can be described by defining appr opriate "weak-process states," which are superpositions of mass eigens tates weighted by their transition amplitudes in the process under con sideration. In the extreme relativistic limit, the weak-process states reduce to the usual weak states. Some numerical examples are given to illustrate the magnitude of nonrelativistic corrections to the standa rd results.
