H-3 And He-3 Electromagnetic Form-Factors

We report the results of three experiments on elastic electron scattering from H-3 and He-3. A detailed description of the experiments and the data obtained is given. We have performed a combined analysis of the world data on H-3 and He-3. This analysis gives a complete experimental information on the trinucleon electromagnetic form factors up to q(2) = 30 fm(-2), and also provides a separation into the isoscalar and isovector form factors. The results are compared to selected calculations that include nucleonic and mesonic degrees of freedom.
