摘要：

Light-cone Lambda(b)(0) and Lambda(c)(+) wavefunctions are constructed to calculate their electromagnetic form factors. A new method is presented to calculate the trace and nontrace parts of the current matrix elements and get analytic expressions which are useful to elucidate numerical results.
