Matter Equation of State with a Three - body Force
The finite temperature Brueckner-Hartree-Fock approach is extended by introducing a microscopic three-body force. In the framework of the extended model, the equation of state of hot asymmetric nuclear matter and its isospin dependence have been investigated. The critical temperature of liquid-gas phase transition for symmetric nuclear matter has been calculated and compared with other predicti...
متن کاملNuclear matter EOS with a three-body force
The effect of a microscopic three-body force on the saturation properties of nuclear matter is studied within the Brueckner-Hartree-Fock approach. The calculations show a decisive improvement of the saturation density along with an overall agreement with the empirical saturation point. With the three-body force the symmetry energy turns more rapidly increasing with density, which allows for the...
متن کاملMicroscopic three-body force for asymmetric nuclear matter
Brueckner calculations including a microscopic three-body force have been extended to isospin asymmetric nuclear matter. The effects of the three-body force on the equation of state and on the single-particle properties of nuclear matter are discussed with a view to possible applications in nuclear physics and astrophysics. It is shown that, even in the presence of the three-body force, the emp...
متن کاملA Generalized Equation of State for Hot, Dense Matter
An equation of state for hot, dense matter is presented in a form that is suuciently rapid to use directly in hydrodynamical simulations, for example, in stellar collapse calculations. It contains an adjustable nuclear force that accurately models both potential and mean-eld interactions, and it allows for the input of various nuclear parameters, some of which are not yet experimentally well-de...
متن کاملMicroscopic nuclear equation of state with three-body forces and neutron star structure
We calculate static properties of non-rotating neutron stars (NS’s) using a microscopic equation of state (EOS) for asymmetric nuclear matter. The EOS is computed in the framework of the Brueckner–Bethe–Goldstone many–body theory. We introduce three-body forces in order to reproduce the correct saturation point of nuclear matter. A microscopic well behaved EOS is derived. We obtain a maximum ma...
