| 英文摘要 | Parity-violating electron scattering (PVS) is an accurate and model-independent way to investigate the weak-charge density distributions of nuclei. In this paper, we study parity-violating electron scattering with the Helm model where the effects of spin-orbit currents on nuclear weak skins are taken into account. The conditions of two PVS measurements to constrain the surface thickness sigma(W) of Helm weak-charge densities are investigated. According to the plane wave Born approximation, A(pv) is expressed in terms of parameters of the corresponding Helm charge and weak-charge densities. After fitting the results of A(pv) calculated from the phase-shift analysis method where the Coulomb distortion effects are incorporated, an empirical formula in terms of Helm model parameters for calculating A(pv) is obtained. If two PVS measurements with different scattering angles are carried out, the modeled weak-charge density distributions with two parameters could be extracted from this empirical formula. |
