Abstract An account is given of recent theories by Brueckner, Eden, Swiatecki, Bethe, and co-workers about the properties of nuclear matter, which is identical in content, but different in its method of presentation. This presentation tries to clarify the reasons for the applicability of the independent-particle model and to determine what particular

Rotating nuclear matter is defined as the system of infinitely many nucleons in a rotating frame neglecting the electrostatic interaction and centrifugal single-nucleon potential. We study the ground state of this system as a function of the densities of neutrons and protons. In the limit where the angular velocity is much smaller than the Fermi energy,

Physical Review, 1961
The methods of quantum statistics previously developed 0ry the author are applied to the determination of properties of the ground state of nuclear matter. An expansion in powers of the pair-function of quantum statistics is made and expressions are derlved for the momentum distribution, pair-correlation function, binding energy, and effective single ...

Physical Review C, 1992
We use the toy model of baryon bag formation to study the changes in the structure of a nucleon when it is placed in nuclear matter. Several interesting qualitative results have been found. We find that ${\mathit{M}}^{\mathrm{*}}$, the nucleon mass in nuclear matter, does not scale with ${\mathit{F}}_{\mathrm{\ensuremath{\pi}}}^{\mathrm{*}}$, the ...

Physical Review Letters, 1960
Equations for explicit Hartree states of energy lower than that of conventional ground states for noninteracting Fermi gases are given for Fermi gases with attractive interactions. One-dimensional and three-dimensional cases are treated. Large static density waves are shown to exist in such Fermi gases, and the binding energy is derived therefrom.

Nuclear forces and the properties of nuclear matter
Annals of Physics, 1960Abstract The application of the Brueckner theory to the nuclear many-body problem can be greatly simplified if one separates the two-nucleon interaction (for any given state and relative momentum) into a short range part vs and a long range part vl. The cut is made such that vs alone gives no phase shift for free particle scattering.

Combustion of nuclear matter into strange matter
Physical Review D, 1994We study the properties of the combustion of pure neutron matter into strange matter in the framework of relativistic hydrodynamical theory of combustion. Because of the uncertainties in the actual properties of neutron matter, we employ the free neutron, Bethe-Johnson, Lattimer-Ravenhall, and Walecka equations of state and for strange matter we adopt ...

Nuclear reactions in nuclear matter
Nuclear Physics, 1966Abstract A number of topics in nuclear reaction theory are examined from the point of view of the liquid drop model. It is shown that, although the absolute value of the nucleon strength function at low energies has significance for high-energy experiments, it cannot be deduced from low-energy elastic scattering experiments, since the energy ...

Hyperfine Interactions, 1978
The present knowledge of the distribution of neutrons and protons in the nucleus is reviewed. The distributions calculated by the single-particle potential method and from the Hartree-Fock theory are compared with the experimental data. Particular attention is paid to the hyperfine anomaly and the isotope shifts, and to the connection with the ...
