We have performed a search for the rare kaon decay [ital K][sub [ital L]] [r arrow] [mu][ital e] at Brookhaven. Finding no events, we set a limit of [ital B]([ital K][sub [ital L]] [r arrow] [mu][ital e])[lt]8.4[times]10[sup [minus]11] (90% confidence level) with a 5% systematic uncertainty. This is a significant improvement over previous results. In addition, we measured the branching ratio of [ital K][sub [ital L]] [r arrow] [mu][mu]; after finding 284 of these events, we calculate a branching ratio of [ital B]([ital K][sub [ital L]] [r arrow] [mu][mu])=(7.6[plus minus]0.5[plus minus]0.4)[times]10[sup [minus]9].
