摘要：

Based on relativistic constituent quark (RCQ) model, the electric and magnetic form factors are analyzed. The ratio of the two form factors for the proton G(Ep)/G(Mp), which is an image of its charge and magnetization distributions, is calculated in the light-front formulism of RCQ model. Recently, this ratio was measured at the Thomas Jefferson National Accelerator Facility (JLab) using the polarization technique. The new data presented span the range 3.5 GeV2 < Q(2) < 5.6 GeV2 and are well,described by a linear Q(2) fit. Also, the ratio rootQ(2)F(2p)/k(p)F(1p) reaches a constant value while Q(2) becomes larger than 2 (GeV)(2). Our calculation results are presented and appear to be consistent with the experimental ones.
