Argonne Physics Division Seminar - 2 Mar 2015

3:30 PM, Building 203, R150!!!!!

In this talk I present a number of Quantum Monte Carlo calculations of
electromagnetic observables for *A* ≤ 10 nuclei, including magnetic
moments, M1 and E2 transitions. In the calculations, wave functions are
generated from nuclear Hamiltonians with two- and three-body realistic
potentials. In addition to the Impulse Approximation contribution, the
nuclear electromagnetic current operator accounts for two-body effects
due to the coupling of external photons with pairs of interacting
nucleons. The two-body operators have been derived from a chiral
effective field theory with pions and nucleons and consist of
contact-like as well as one- and two-pion exchange operators. When used
in combination with realistic nuclear Hamiltonians, two-body effects are
found to be sizable and not negligible in a careful interpretation of
the experimental data.
