    Parameterizations of Electron Scattering Form Factors for Elastic Scattering and Electro-Excitation of Nuclear States for and

    Arie Bodek · M. E. Christy · Zihao Lin · Giulia-Maria Bulugean · Amii Daniela Matamoros Delgado

    We report on empirical parameterizations of longitudinal () and transverse () nuclear electromagnetic form factors for elastic scattering and the excitations of nuclear states in and . The parameterizations are needed for the calculations of radiative corrections in measurements of electron scattering cross sections on and in the quasi-elastic, resonance and inelastic continuum regions, provide the contribution of nuclear excitations in investigations of the Coulomb Sum Rule, and test theoretical model predictions for excitation of nuclear states in electron and neutrino interactions on nuclear targets at low energies.

    Perturbation theory for a systematic account of the bound-state motion

    Alexander N. Kvinikhidze🇬🇪 · Hagop Sazdjian🇫🇷 · Boris Blankleider🇦🇺

    We derive a perturbation theory (PT) for the Lorentz boost operator in the space of two-nucleon wave functions. The latter is expressed in terms of the nucleon-nucleon () potentials, developed so far in great detail for their use in the scattering studies. The PT is designed to take into account the boost relativistic corrections in a systematic way and, as such, it is the only missing part in the corresponding approaches developed up to now in the low-energy effective field theories.

    Heisenberg Uncertainty Inequality and Breaking of Isospin Symmetry in Atomic Nuclei

    Sandro Stringari🇮🇹

    The Heisenberg uncertainty inequality is used to derive a rigorous lower bound to the amount of isospin impurities in atomic nuclei, caused by the violation of isospin symmetry. The bound is fixed by the difference between the neutron and proton radii and the sum of the charge exchange monopole strengths. It can be used to check the consistency of advanced many-body calculations accounting for the breaking of isospin symmetry. The uncertainty inequality is also employed to derive an upper bound to the isovector dipole moment in terms of the amount of isospin impurities, providing an insightful connection between the violation of parity and isospin symmetries.
