The convergence of the ab-initio many-body expansion for the cohesive energy of solid mercury

Beate Paulus, Krzysztof Rosciszewski, Nicola Gaston +2

A many-body expansion for mercury clusters of the form E = \sum_{i<j}Δε_{ij} + \sum_{i<j<k}Δε_{ijk} + ... \quad, does not converge smoothly with increasing cluster size towards the…
