摘要：

A constituent quark model is developed for an arbitrary light-cone direction so that the light-front time is x(LF)(+) = omega . x with a constant lightlike four-vector omega. Form factors are obtained from free one-body electromagnetic current matrix elements. They are found to be omega-independent for spin-O mesons, nucleons and the Lambda-hyperon, while there is an omega-dependence for spin-1 systems like the deuteron.
