Is it possible to observe positron-matter complexes before positron-electron annihilation? In a new paper published in The Journal of Chemical Physics by Hylleraas members Einar Aurbakken, Håkon Emil Kristiansen, Simen Kvaal, and Thomas Bondo Pedersen along with Antoine Camper from the Department of Physics at UiO, theoretical simulations of photopositron spectra predict that the answer is yes!

In a project led by Jonas Mikkelsen and Frank Jensen at Aarhus University in Denmark, Simen Reine and Thomas Bondo Pedersen have published a new paper on the decomposition of molecular polarizabilities from coupled-cluster and MCSCF theory into atomic charge flow and induced dipole contributions. The results may support improved parameterizations of polarizable force fields for molecular dynamics simulations.
