Analysis of parity-violating asymmetries in elastic electron-nucleus scattering
Parity violating asymmetries in elastic electron scattering on nuclei with arbitrary spin and isospin are considered in detail, extending our previous work on this matter [1]. Examples are given for the target nuclei12C,40Ca,208Pb,3H,3He,41Ca,209Bi. Several ways of extracting information on the structure of weak neutral current couplings are presented. Besides, as a further possibility to check the validity of the standard gauge model [2] at intermediate energies, the chances to distinguish among different classes of gauge models are discussed.
Parity-violating asymmetry in elastic electron-nucleus scattering due to weak neutral currents
Parity-violating asymmetries are calculated for elastic scattering of electrons on nuclei of arbitrary spin and isospin. Possible dependences on nuclear-model input are shown to be weak. Elastic electron scattering at intermediate energies may become an important tool in studying the structure of hadronic weak neutral currents.
