Inelastic electron scattering on 16O and nuclear models

Form factors (FF) and transition charge densities (TCD) obtained during investigation of 16O nucleus electrical excitation are compared with the results of calculations on the Helm model and hydrodynamic models to detect the possibilities for macromodels in FF description and independent in simulation TCD of low-lying collective states in 16O. Analysis shows that the models used (the Tassi model and its modification, the modified Steinwedel -Jiencen model, the Boron-Mottelson model) in some cases agree well with experimental results although they do not describe all data. Investigation of monopole (O1+ and O2+) and dipole (11-) transitions in 16O points to deep volume oscillations, which are absent in transitions with λ=2, 3, 4 - their TCDs are of the surface character
