NUCLEAR ELECTRODISINTEGRATION WITH NUCLEON EMISSION

The emission of single nucleons by the scattering of electrons from nuclei is investigated. Centre-of-mass and relative coordinates are used since this avoids the Gartenhaus-Schwartz transformation and associated difficulties. The Hamiltonian describing the interaction between the electron and the nucleons is expanded in multipoles, and it is found possible to perform several of the summations over final- state angular momentum quantum numbers. The resulting formulae are applied to the electrodisintegration of 12C, and comparison is made with experiment. It is of interest that, as regards the position of the maximum in the cross section, agreement with experiment is improved by introduction of a final-state interaction, which is taken to be real and central. However, the magnitude of the cross section is about twice as large as the experimental value, even allowing for uncertainties in the experimental result.
