Lowest order constrained variational calculation for nuclear and neutron matter with a new charge-dependent Reid potential

摘要

The lowest order constrained variational (LOCV) method is reformulated to calculate the equation of state of nuclear and neutron matter with a new charge-dependent Reid potential (Reid93). The state-dependent correlation functions are calculated by performing a full functional minimization for each JLSTM(T)-channel and the resulting Euler Lagrange equations are solved up to J = 9. The correlation functions are compared with those coming from LOCV calculation with the old Reid68 potential. It is shown that unlike Delta-Reid68 and AV(18) interactions, the new Reid93 over binds nuclear matter at much larger saturation density than Reid68. Finally, the results are being compared with similar calculations with other potentials and many-body techniques.
