Abstract
In this article it is attempted to separate σ_tot into longitudinal, σ_Land transverse, σ_T cross-sections and to calculate charged Kaon form factor. The Jlab 2001 (E98-108) data has been used and Rosenbluth separation technique is applied to charged kaon electroproduction at Q^2=1.9〖 and 2.35 (GeV/c)〗^2 in different energies. Data were taken at electron beam energies ranging from 3.40 to 5.75 (GeV).Charged kaon form factor is determined at Q^2=1.9〖 and 2.35 (GeV/c)〗^2 by using Chew-low technique and Regge model. Influence of the kaon pole on the cross-sections is investigated by adopting an off-shell form factor in the Regge model, which better describes the observed energy dependence of σ_T and σ_L.
