BETHE-BRUECKNER-GOLDSTONE EXPANSION IN NUCLEAR-MATTER

The equation of state of symmetric nuclear matter at zero temperature is calculated up to the three hole-line level of approximation in the Bethe-Brueckner-Goldstone expansion. Both the standard and the continu ous choices for the single particle auxiliary potential are considered . The resulting equation of state shows independence from the choice o f the auxiliary potential to a high degree of accuracy. This result gi ves strong evidence for the convergence of the expansion and establish es the nuclear matter saturation curve fur the adopted nucleon-nucleon interaction, the Argonne v(1+) potential.
