摘要：
In this paper, the effects of shape coexistence on the resulting mixed configuration of the ground state are investigated by elastic electron scattering. The shape configurations of ground states are searched by the constraint relativistic mean-field (RMF) model. For nuclei with shape coexistence, the density distributions of the coexistence states are obtained from the mixing of different configurations. With the charge distributions, the Coulomb form factors vertical bar F-C(q)vertical bar(2) of the coexistence states are calculated by the distorted wave Born approximation method. By comparing the vertical bar F-C(q)vertical bar(2) of coexistence states with the vertical bar F-C(q)vertical bar(2) of certain shape configurations, the phenomena of the shape coexistence can be analyzed by electron scattering.
