Structure of theHe3Nucleus

Abstract

The ${\mathrm{He}}^3$ nucleus has been investigated by means of the elastic electron scattering technique. Experiments were carried out in the energy range 110-650 MeV. Absolute differential cross sections were measured at angles lying between 40° and 135° in the above energy range. Form factors were observed for both the charge density and magnetic moment density of the ${\mathrm{He}}^3$ nucleus. The results indicate that the charge cloud may be represented best by a model similar to a hollow exponential I type of rms radius 2.05 F. The magnetic moment cloud can be represented approximately by a Gaussian model of rms radius 1.66 F. There appears to be a difference between the gross features of the charge and magnetic moment clouds, and the magnetic moment cloud appears to be the more compact of the two.
