Electromagnetic Structure of theHe3Nucleus

The electromagnetic structure of the ${\mathrm{He}}^3$ nucleus has been investigated by means of high-energy electron scattering. A separation of the charge and magnetic form factors has been accomplished. The charge form-factor data extend to $q^2=20\mathrm{}$ ${\mathrm{fm}}^{-2\mathrm{}}$ and exhibit a diffraction minimum at $q^2=11.6\mathrm{}$ ${\mathrm{fm}}^{-2\mathrm{}}$; the magnetic scattering is measured to $q^2=12.5\mathrm{}$ ${\mathrm{fm}}^{-2\mathrm{}}$. The results are discussed in terms of models for the charge and magnetic distributions of the nucleus.
