| Abstract: | We propose a new method for measuring the difference $Delta f = f(0) - bar f(0)$ of the forward scattering amplitudes for K0 and $bar K^0 $ by use of decay rates of initially pure strangeness states after passage through a regenerator. The phenomenology of coherent kaon regeneration is presented for arbitrary mixtures of K0 and $bar K^0 $ . |
