相対論的平均場近似を越える試みとして核内二核子間相関が、相対論的Brueckner-Hartree-Fock流の方法で計算される。方程式は相対論的波束展開法を用いて解かれる。中間子交換parameterはBonn A potentialより採用され、Fourth-order計算がすでに実験結果を良く再現していることが示される。
The compressional properties of nuclear matter are studied by using the relativistic mean field theory with the vector self-interactions. The parameters of the model are determined so as to account for both the empirical compressional properties and the empirical spin-orbit potential. The obtained EOS is very close to the results of the Dirac-Brueckner-Hartree-Fock calculation.
The thermodynamic potential for nuclear matter including the relativistic correlation parts is calculated in the σ-ω model based on the 1/N expansion scheme. The equation of state of nuclear matter at finite density and temperature is investigated.
