A measurement of the form factor ratios in the decay D+ → K*(892)0μ+ν is obtained by fitting to the decay angles and q2 of 305 events. The results, evaluated at q2 = 0, are A2(0)/A1(0) = 0.82+0.22-0.23 (stat.)±0.11 (sys.) and V(0)/A1(0) = 2.00+0.34-0.32±0.16, where A1 and A2 are the axial vector form factors and V is the vector form factor. The corresponding ratio of the longitudinal to transverse polarization of the K*0 is 1.18±0.18±0.08. These results are compared with other experimental results and with theoretical predictions.
