    Abstract
    Using the CLEO II detector at the Cornell Electron Storage Ring, we have searched for flavor changing neutral currents and lepton family number violations in D-0 meson decays. The upper limits on the branching fractions for D-0 --> l(+)l(-) and D-0 --> X(0)l(+)l(-) are in the range 10(-5) to 10(-4), where X(0) can be a pi(0), K-s(0), eta, rho(0), omega, (K) over bar(*0) or phi meson, and the l(+)l(-) pair can be e(+)e(-), mu(+)mu(-), or e(+/-)mu(-/+). Although these limits are above the theoretical predictions, most are new or an order of magnitude lower than previous limits.
