Abstract：
Recently,the ratio of electric form factor to magnetic form factor for the neutron GEn/GMn,which contains important pieces of information on the internal structure of nucleon,was measured at the Thomas Jefferson National Accelerator Facility(JLab).The traditional relativistic constituent quark(RCQ)model appears to be successful in explaining the two form factors for the proton GEp/GMp,however the calculation results for the neutron is much bellow the experiments.For interpreting this phenomenon,we investigate the effects of SU(6) breaking.It is shown that the calculation results gets better close to experiments.
