Title: Electromagnetic structure of the trinucleons

Abstract

The electromagnetic form factors of the trinucleons {sup 3}H and {sup 3}He are calculated with wave functions obtained with the Argonne AV18 two-nucleon and Urbana IX three-nucleon interactions. Full account is taken of the two-body currents required by current conservation with the AV18 interaction as well as those associated with N-Delta transition currents and the currents of Delta resonance components in the wave functions. Explicit three-nucleon current operators associated with the two-pion exchange three-nucleon interaction arising from irreducible S-wave pion-nucleon scattering is constructed and shown to have very little effect on the calculated magnetic form factors. The calculated magnetic form factor of {sup 3}H, and charge form factors of both {sup 3}H and {sup 3}He are in satisfactory agreement with the experimental data. However, the position of the zero in the magnetic form factor of {sup 3}He is slightly underpredicted.
