Description
The electron-nucleus scattering provides us with one of the clearest ways to investigate nuclear structure. The scattering cross is factorized as a product of the leptonic and nuclear parts. The nuclear part can be computed from the nuclear vector current operators. With chiral effective field theory, the current operators can also be derived systematically, the same as the nuclear interactions. With polynomially scaling many-body methods such as the coupled-cluster method and in-medium similarity renormalization group approach, ab initio calculations of medium-mass nuclei are becoming possible. In this talk, I will present the computed results of radii and the effect of the two-body current on magnetic observables for medium-mass nuclei.
