摘要：

The Equation of State of pure neutron matter at zero temperature is calculated up to the three hole-line level of approximation in the Bethe-Bmeckner-Goldstone expansion. The calculations are performed for the Av(14) and the Av(18) nucleon-nucleon potentials, up to the Fermi momentum k(F) = 2.8 fm(-1). The three hole-line contribution turns out to be smaller than in symmetric nuclear matter, and indeed a minor correction if the so-called "continuous choice" for the single particle potential is adopted. These findings are in line with the corresponding values of the wound parameter. The results are expected to be relevant for the theory of neutron stars structure.
