Theory of Inelastic Electron Scattering by theC12Nucleus

Abstract

The recently measured elastic and inelastic electron scattering cross sections of ${\mathrm{C}}^{12}$ are utilized to test the shell model of light nuclei. Collective effects are important in the excitation of two of the excited states (7.68 and 4.42 Mev), and are acceptably accounted for by the independent-particle approach to collective oscillations recently proposed by the authors. The inelastic scattering data leading to the 9.61 Mev state are shown to identify it as probably ${1}^{\ensuremath{-}}$. Some of the results of higher energy scattering experiments on ${\mathrm{C}}^{12}$ and ${\mathrm{O}}^{16}$ are predicted.
