The theory of [ital CP] violation based on phases in weak couplings in the Cabibbo-Kobayashi-Maskawa matrix requires the phase [gamma][equivalent to]Arg[ital V][sub [ital u][ital b]][sup *] (in a standard convention) to be nonzero. A measurement of [gamma] is proposed based on charged [ital B] meson decay rates to [pi][sup +][ital K][sup 0], [pi][sup 0][ital K][sup +], [pi][sup +][pi][sup 0], and the charge-conjugate states. The corresponding branching ratios are expected to be of the order of 10[sup [minus]5].
