- W129175849 abstract "Transition charge densities for states of electric type, for nuclei with Aless than or equal to40--50 as obtained from data on inelastic electron scattering, are studied. The formalism of electroexcitation of nuclei is considered, together with various models (macroscopic and microscopic) used to calculate form factors, transition charge densities, and the moments of these densities: B(Elambda) and R/sub lambda/ . The macroscopic models are derived microscopically, and it is shown that the model-independent sum rules lead to the same transition densities as calculations based on various hydrodynamic models. The sum rules with and without allowance for the Skyrme exchange interaction are discussed. The results of the calculations are compared with the experimental form factors of electron scattering by nuclei from /sup 12/C to /sup 48/Ca with excitation in them of normal-parity states with I/sup ..pi../ = 0/sup +/ , 1/sup -/ , 2/sup +/ , 3/sup -/ , 4/sup +/ , 5/sup -/ and T = 0. The model-independent transition charge densities for the weakly collectivized excitations differ strongly from the model-dependent densities. The influence of neutrons on the transition charge densities of the nuclear isotopes /sup 16//sup ,//sup 18/O, /sup 32//sup ,//sup 34/S, and /sup 40//sup ,//sup 48/Ca ismore » considered.« less" @default.
