The usual phenomenology of the complex formed by a neutral flavoured meson M0 and its antiparticle assumes the absence of vacuum regeneration in this complex. We propose experiments for determining the two amplitudes of (possibly non-zero) vacuum regeneration: (i) a comparison of the time dependence of decays of the M0 and into a channel which could be a CP-eigenstate (e.g., or ), or a general channel like ; (ii) a measurement of the ratio of the time-dependent transmutations, and ; (iii) a measurement of the ratio of the time-dependent probabilities for the production of and states, starting with a C-odd correlated state like the -meson. The proposed experiments are required to be as accurate as those for the known CP-violation effects in the complex.
