Inelastic Electron Scattering from Levels at 19.5-MeV Excitation inC12

Abstract

An apparently good fit of the summed transverse and longitudinal form factors to the total measured form factor for inelastic electron scattering to the 19-MeV levels of ${\mathrm{C}}^{12}$ appears less good when the two components are distinguished. Evidence for the $T=1\mathrm{}$, $J=1^{-}$ and $T=1\mathrm{}$, $J=2^{-}$ states seems clearly established, but the longitudinal form factor indicates that another level is contributing.
