The simplest version of Chou-Yang model is employed to extract the form factor by fitting experimental data of differential cross section from TOTEM experiment (for 13 &#963;Beam and 4.3 distance) to a single Gaussian. Root mean square charge radius of proton is calculated using this form factor and is found to be equal to 0.91 fm and 0.90 fm, respectively. This result is in good agreement with experimental data and theoretically predicted values.]]></p></abstract>
