Many-body problem for strongly interacting particles. II. Linked cluster expansion. Brueckner, K. A. *Physical Review*, 100(1):36–45, oct, 1955. Paper doi abstract bibtex An approximation method developed previously to deal with many particles in strong interaction is examined in further detail. It is shown that the series giving the interaction energy is a development in a sequence of linked or irreducible cluster terms each of which gives a contribution to the energy proportional to the total number of particles. Consequently the convergence of the expansion is independent of the total number of particles. The origin of this simple feature is illustrated by showing that a similar situation exists in the expansion of standard perturbation theory. The numerical convergence of the expansion is quantitatively discussed for the nuclear problem where it is shown that the correction arising from the first cluster term involving three particles is less than the leading term by a factor of about 10-4. The smallness of the correction is largely a result of the action of the exclusion principle. \textcopyright 1955 The American Physical Society.
