摘要：

We present a measurement of the form-factor ratios r(v) = V(0)/A(1)(0) and r(2) = A(2)(0)/A(1)(0) for the decay D+ --> (K) over bar(*0)e(+) nu(e). The measurement is based on a signal of approximately 3000 D+ --> (K) over bar(*0)e(+) nu(e), (K) over bar(*0) --> K- pi(+) decays reconstructed in data from charm hadroproduction experiment E791 at Fermilab. The results are r(v) = 1.84 +/- 0.11 +/- 0.08 and r(2) = 0.71 +/- 0.08 +/- 0.09.
