Employing the decay chain [ital K][sup +][r arrow][pi][sup +][pi][sup 0], [pi][sup 0][r arrow][ital e][sup +][ital e[minus]] we have observed the decay [pi][sup 0][r arrow][ital e][sup +][ital e[minus]]. With a signal sample of [approx]21 events we measure the branching ratio for [pi][sup 0][r arrow][ital e][sup +][ital e[minus]] to be (6.9[plus minus]2.3[plus minus]0.6)[times]10[sup [minus]8], normalized to the decay [ital K][sup +][r arrow][pi][sup +][pi][sup 0], [pi][sup 0][r arrow][ital e][sup +][ital e[minus]][gamma]. This result is consistent with the unitarity lower bound and the published 90% confidence level upper limit of 13[times]10[sup [minus]8].
