Tritium form factors at lowq

Abstract

The elastic charge and magnetic form factors of $^{3}\mathrm{H}$ have been measured in the region $0.0477<{q}^{2}<2.96$ ${\mathrm{fm}}^{\ensuremath{-}2}$. Throughout this range, the charge form factor is found to be larger than previous measurements, whereas the magnetic form factor agrees with the earlier work. The change in the charge form factor slightly increases the discrepancy between the calculated and observed binding energy difference between $^{3}\mathrm{H}$ and $^{3}\mathrm{He}$.
