He3charge form factors by nuclear recoil detection

${}_{}{}^3{}_{}{}^{}\mathrm{He}$ charge form factors were measured by observing the scattering reaction ${}_{}{}^3{}_{}{}^{}\mathrm{He}$(e,${}_{}{}^3{}_{}{}^{}\mathrm{He}$)e from square momentum transfers 0.885 to 3.20 ${\mathrm{fm}}^{-2\mathrm{}}$. The results compare favorably with earlier electron scattering experiments. A model-independent determination of the radial charge density gives an rms radius of 1.877±0.019 fm, in excellent agreement with previous radii determinations.
