The aim of the present work is to investigate the charge structure of neutron by calculating its root mean square charge radius 〈rn2〉1/2 and the corresponding charge form factor,Gn(q), within the general framework of quark-parton model. The neutron (the nucleon in general) is considered to be disc-like in conformity with the idea of Lorentz invariance. Using the proton charge radius, 〈rp2〉=0·707 fm2 as input, our calculations not only reproduce the observed negative sign correctly but also give reasonable value for the magnitude of 〈rn2〉 when compared with the experimental limits. −0·16≦〈rn2〉≦−0·11 (fm2). Predictiona are also made for the proton and the neutron charge form factors and the results compared with the data.
