The ground-state charge distribution of the silicon isotopes and the excited states of28Si,30Si

Abstract
The ground-state charge distributions of 28,29,30Si have been studied by elastic electron scattering and the results compared with those from muonic isotope shift work and other electron-scattering experiments. The 21+ state at 1.78 MeV in 28Si and the 21+ state at 2.24 MeV and 22+ state at 3.50 MeV in 30Si have been investigated by inelastic electron scattering and their form factors extracted.
