Abstract : The four form factors in electrontrinucleon (eH3 or eHe3) elastic scattering are analyzed using two alternative sets of four unknowns: (i) the neutron electric form factor, the form factor F for the dominant S state and the isovector and isocalarexchange magnetic form factorsneglecting the mixed symmetry S' state; (ii) the form factors for odd and like nucleons, and the isovector and isocalarexchange magnetic form factorsassuming knowledge of the neutron electric form factor, essentially 0.02 qsquared. The first alternative gives positive neutron electric form factors that seem somewhat high; the second alternative gives a plausible value of 1% for the probability of the mixedsymmetry S' state, and also gives a reasonable shape for the isovectorexchange form factor. The isocalarexchange form factor stays less than 0.06 nm. Good agreement is found between results for F and calculations based on three different wave functions adjusted to give the experimental Coulomb energy. (Author)
