Abstract
The dynamics of the decay D(s)+ --> phie + nu(e) are studied using a s ample of 474 events recorded by the CLEO II detector. A three dimensio nal fit to the decay angles and q2 is performed to extract the ratios of form factors R2 = A2(0)/A1(0) and R(v) = V(0)/A1(0), where A1(0) an d A2(0) are the two axial vector form factors and V(0) is the vector f orm factor evaluated at q2 = 0. By assuming the single pole parameteri zation for the form factors, we obtain: R2 = 1.4 +/- 0.5 +/- 0.3 and R (v) = 0.9 +/- 0.6 +/- 0.3.
