Starting with a {ital C}-odd state (for example, {phi},{Upsilon}(4{ital S})) made out of a neutral flavored meson {ital f} and its antiparticle {ital {bar f}}, the probability for producing the state {ital ff} has the same double time dependence as the corresponding probability for producing the state {ital {bar f}} {ital {bar f}}.
