It is shown that the weak states which are used in the standard treatment of neutrino oscillations do not, in general, describe correctly the neutrinos produced and detected in weak-interaction processes. It is also shown that it is impossible to construct a Fock space of weak states. However, neutrino oscillations can be described by defining appropriate weak-process states,'' which are superpositions of mass eigenstates weighted by their transition amplitudes in the process under consideration. 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 standard results.
