Abstract
Using 3.0 fb(-1) of data collected with the CLEO-II detector, we study the Cabibbo-suppressed decay D-0-->pi(-)e(+)nu(e). The ratio of the b ranching fractions B(D-0-->pi(-)e(+)nu(e))/B(D-0 -->K(-)e(+)nu(e)) is measured to be (10.3+/-3.9+/-1.3)%, corresponding to an upper limit of 15.6% at the 90% confidence level.
