Determination of Radiative Transition Widths of Excited States inC12

New absolute values for the elastic and inelastic electron-scattering cross sections from ${\mathrm{C}}^{12}$ are presented for a range of $q^2$ from 0.75 to 3.14 ${\mathrm{F}}^{-2\mathrm{}}$. A new method of analysis has been employed to obtain the radiative widths for the first three excited states in ${\mathrm{C}}^{12}$ from the measured inelastic cross sections. This method of analysis does not depend on a model for the transition charge distribution and is useful in determining the multipolarity of the transition.
