ELASTIC AND INELASTIC ELECTRON SCATTERING FROM C12 AND O16,

Abstract

Elastic and inelastic electron scattering from C12 and O16 has been studied for various scattered electron angles, using primary beam energies from 600 to 800 MeV. These studies cover a range of the square of the momentum transferred to the nucleus. A procedure for subtracting the effects of energy loss due to radiation of the electrons is developed. With the resolution obtained in this experiment it is possible to resolve elastically scattered electrons from inelastically scattered electrons. In many instances it is also possible to resolve electrons which have excited discrete nuclear levels in C12 and O16. Inelastic electron scattering due to excitation of nuclear levels is observed from the 4.43 MeV, 2(+) and 9.6 MeV, 3(-) levels in C12; and for the 6.1 MeV levels in O16. Differential cross sections for excitation of these levels as well as for elastic scattering are determined. Absolute values of the cross sections are obtained by comparison with known absolute proton cross sections. Analysis of the data using first Born approximation shows that the root mean square radii of C12 and O16 are 2.40 + or -0.02 F and 2.65 + or -0.04 F respectively. (Author)
