Elastic Form Factors of 3,4He up to Large Q2

摘要

Elastic electron scattering off 3He and 4He has recently been stud- ied at forward and backward scattering angles in Hall A at JLab. The results will provide accurate data on the elastic form factors, charge and magnetic for 3He and charge only for 4He, up to squared momentum transfer Q2-values of 3.2 GeV2.
