Three-Body Problem in Nuclear Matter

This work reviews some recent developments in the theory of nuclear matter. Assuming familiarity with the basic Brueckner-Goldstone theory described in the preceding article by B. Day, it is first shown that the Brueckner-Goldstone series does not converge in powers of the reaction matrix, and that the perturbation series for the binding energy has to be rearranged in powers of the density $\rho$. Physical reasons and actual estimates are provided for expecting convergence in powers of $\rho$.
