Abstract

Longitudinal and transverse electromagnetic form factors of the ⁷Li ground-state doublet (the J^π= 3 2^- ground state and the E_x=478 keV, J^π= 1 2^- first excited state) were measured by electron scattering up to momentum transfers of 4.2 and 4.5 fm^-1, respectively. The transverse form factors show no diffraction structures in the high momentum transfer region which could be unambiguously identified as signatures of meson-exchange currents; however, they lie above existing calculations which do not include such contributions. The longitudinal elastic form factor has a second maximum as does the C2 form factor of the first excited state.
