The deuteron form Factors are calculated in the framework of the relativist
ic nucleon-meson dynamics, by means of the explicitly covariant light-front
approach. At Q(2) less than or equal to 3 (GeV/c)(2) the prediction for th
e structure function A(Q(2)) and for the tensor polarization observable t(2
0) are in agreement with the recent data of CEBAF/TJNAF.
