Bond oscillation, a phenomenon characteristic of the molecular electron-density distribution in momentum space, is demonstrated for the 1σg molecular orbital of H2 with an (e, 2e) experiment at large momentum transfer. Analysis of the experimental data in terms of two-center interference effects has revealed that different oscillatory structures can be observed, depending on the model for describing (e, 2e) ionization from the constituent H 1s atomic orbitals. It is shown that bond oscillation is highly sensitive to the spatial pattern and chemical bonding nature of the molecular orbital.
