Abstract: Extension and surface diffuseness parameters of Gambhir-Patil (GP) semi-phenomenological proton, neutron and their weighted average densities have been calculated for a large number of nuclei in the mass number range 12≤A≤238 following the method proposed by Friedrich and Voegler [Nucl Phys A, 373 (1982) 192] who used it to study the salient features of nuclear charge density distribution. It is found that the extension parameter (diffraction radius) values of the GP proton density are in good agreement with those extracted from the experimental charge form factors. The corresponding surface diffuseness parameter values are also in reasonably good agreement with the experimental values with some exceptions. The mass number dependence of the diffraction radii and diffuseness parameters of the GP proton, neutron densities, and their average have been studied.
