Abstract:

The saturation curves of nuclear matter are calculated by using the reference spectrum method for the one-boson-exchange potentials with various hard core radii. The hard core radius is varied continuously down to zero without changing the two-nucleon scattering phase shifts up to ∼300 MeV. A Gaussian type soft core potential derived by Tamagaki is also used and the result is compared with that of Harada et al., who calculated with a rather exact method. It is found from this comparison that the reference spectrum approximation is quite good if the reference spectrum parameters are carefully chosen.
From the results obtained by using the one-boson-exchange potentials, it is shown that the soft core potential is more favorable for the binding energy of the nuclear matter than a potential with big hard core radius and that there is no essential difference between the soft core potential and the hard core one core radius of which is smaller than 0.2 fm.
