摘要：Understanding the internal structure of hadrons and atomic nuclei remains an important challenge in low-energy nuclear physics. By measuring form factors (FFs) associated with various interactions, crucial information about local densities of properties like charge, energy, and spin is obtained. While electromagnetic FFs are well-established, measurements of those related to weak forces or gravity are less precise. However, recent advancements in parity-violating scattering experiments have enabled a precise determination of the neutron skin thickness (NST) in heavy nuclei, revealing insights into the isospin breaking part of the strong force by quantifying the disparity between proton and neutron distributions within a nucleus. In this talk, I will demonstrate the computation of local densities and associated radii within the Skyrme model in order to make predictions of the pressure distribution and NST of nuclei, testable against recent and prospective experimental results.
