Abstract
The cross sections for elastic electron scattering from 3He and 4He were measured for the momentum transfer range from 0.45–2.0 fm −1. The cross sections were separated into their longitudinal (charge) and transverse (magnetic) contributions using the Rosenbluth formula. The charge and magnetic form factors were obtained model-independently. The rms charge radii were found to be 1.671 (14) fm for 4He and 1.976 (15) fm for 3He, and the magnetic rms radius of 3He is 1.99 (6) fm. The mis charge radius for 4He is in excellent agreement with the latest muonic data. Comparison of the form factors was made with Faddeev three-body calculations using realistic two-body NN interactions. At present the theoretical calculation is not able to reproduce the experimental data.
