Abstract: (Elsevier)

The behavior of the magnetic form factor of 3 He for momentum transfers q 2 < 30 fm −2 is studied with simple wave function models and with account of pion and ρ-meson exchange current effects. The single-nucleon current contribution to the form factor depends strongly on the D-state probability. The exchange current contributions dominate the form factor for q 2 > 5 fm −2 . The sensitivity of the exchange current contributions to wave function details — short-range correlations and D-state percentage — and hadronic form factors in the exchange operators is investigated in some detail. With inclusion of the ρ-meson exchange effect the predicted position of the form factor minimum is in reasonable agreement with the most recent data. With the exchange effects considered the predicted magnetic moment agrees with the empirical value. The models employed lead to no noticeable difference in the behavior of the triton and helion magnetic form factors.
