Charge Radius Measurements of Some Light Nuclei

The ability of variational Monte Carlo models to calculate the properties of light nuclei has inspired a new generation of elastic scattering measurements. Hall A at Jefferson Lab has now determined the differential cross-section for several light nuclei (H, D,$^6Li$ , $^{10}B$ ,$^{12}C$ ) using beam energies down to 360 MeV beam and spectrometer angles down to $12.5 ^{o}$.The results have been parametrized using a model independent Fourier-Bessel parametrization. For those nuclei where world data exists, we found good agreement. For the boron data, we made use of the NIKHEF suggestion to use $B_4C$ instead of the problematic pure boron. After subtracting the carbon yield from the $B_4C$ data, we obtain the boron cross section from 0.39$fm^{-1}$ to 2$fm^{-1}$ and we will present our preliminary charge radius result for this nucleus.
