    "abstract": "Three well known photonuclear sum rules (SR), i.e. the Thomas-Reiche-Kuhn,\nthe bremsstrahlungs and the polarizability SR are calculated for 4He with the\nrealistic nucleon-nucleon potential Argonne V18 and the three-nucleon force\nUrbana IX. The relation between these sum rules and the corresponding energy\nweighted integrals of the cross section is discussed. Two additional\nequivalences for the bremsstrahlungs SR are given, which connect it to the\nproton-neutron and neutron-neutron distances. Using them, together with our\nresult for the bremsstrahlungs SR, we find a deviation from the tetrahedral\nsymmetry of the spatial configuration of 4He. The possibility to access this\ndeviation experimentally is discussed.",
