Transverse electromagnetic form factor inC12

We calculate the contribution from the convection current to the recently measured transverse form factor of the ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ $2^{+}$ level at 4.44 MeV. The convection current dominates for small momentum transfer and is determined by the $B\left(E2\right)$. In this region, theory agrees with experiment. At intermediate momentum transfer, agreement with experiment is only possible assuming a coherent sum of the convection current and magnetization density contributions.
