摘要
The properties of asymmetric nuclear matter for a wide range of densities and asymmetric parameters are investigated within the lowest-order-constrained variational (LOCV) method by employing the relativistic Hamiltonian with a potential which has been fitted relativistically to N-N phase shifts ((v) over tilde (14)) and to the AV(14) interaction. Like our previous work on symmetric nuclear matter, the boost interaction corrections as well as the relativistic one-body and two-body kinetic corrections are calculated. The various properties of asymmetric nuclear matter such as the symmetry energy, the saturation energy and the validity of the a 2 law, etc., are examined. The symmetry energy is reduced by about 7MeV when we use (v) over tilde (14) instead of its non-relativistic version, i.e. the AV14 interaction. The results are compared with other many-body calculations.
