Electromagnetic form factors of theA=3systems

Abstract

We explore the dependence of the magnetic and charge form factors of ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ and ${}_{}{}^3{}_{}{}^{}\mathrm{H}$ on nucleon structure models and $\mathrm{NN}$ interaction models within the traditional framework of nucleons, isobars, and mesons. We utilize wave functions which incorporate the effect of a genuine three-body force, and include contributions to the nuclear current from a variety of mesonic exchange and isobaric processes. The importance of the high momentum transfer region as a source of information on short-range processes in the nuclear medium is reiterated by our results.
