Abstract
Using 9.0 fb(-1) of integrated luminosity in e(+)e(-) collisions near the Y(4S) mass collected with the CLEO II.V detector we report the first observation of the decay D-0-->K(S)(0)etapi(0). We measure the ratio of branching fractions, BR(D-0-->K(S)(0)etapi(0))/BR(D-0-->K(S)(0)pi(0)) = 0.46+/-0.07+/-0.06. We perform a Dalitz analysis of 155 selected D-0-->K(S)(0)etapi(0) candidates and find leading contributions from a(0)(980)K-S(0) and K*(892)eta intermediate states.
