Abstract

A comprehensive theoretical and experimental investigation of electron scattering on F19 is presented. Theoretical procedures for calculating the various components of electron scattering form factors from multiparticle shell-model wave functions are summarized. These procedures are used to compare shell-model predictions with data from electron scattering on F19. For the positive-parity states of F19 we use 1s0d shell-model wave functions obtained with a new ‘‘universal’’ Hamiltonian and for the negative-parity states we use 0p-1s0d shell-model wave functions based on the cross-shell Hamiltonian of Millener and Kurath. The comparisons are made with measured longitudinal and transverse form factors for momentum transfers up to 2.4 fm1 which are extracted from experimental data obtained with electron energies from 78 to 340 MeV, and angles of 45°, 90°, and 160°. The energy resolution was 2550 keV and most of the known levels below 8 MeV in excitation were resolved and compared with theory.
