Theory of Nuclear Matter

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 ...

Relativistic nuclear structure. I. Nuclear matter

Physical Review C, 1990
The formalism for the Dirac-Brueckner approach to the nuclear many-body problem is described including its basis in relativistic two-nucleon scattering. A family of relativistic meson-exchange potentials is constructed which (apart from the usual coupling terms for heavy mesons) apply the pseudovector (gradient) coupling for the interaction of ...

Nuclear reactions in nuclear matter

Nuclear Physics, 1966
Abstract 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 ...

The Exploration of Hot Nuclear Matter

Science, 2012
The Primordial Soup Protons and neutrons were originally thought to be indivisible, but we now know that they have constituent parts—quarks. Quarks are bound together tightly through gluons and can only come apart under extreme conditions—conditions believed microseconds after the Big Bang to have formed a hot, dense “soup” of ...

Density fluctuations in nuclear matter

Il Nuovo Cimento A, 1975
Variational computations of the binding energy per particle for various models of nuclear matter are reported. The main purpose is to compare the results corresponding to a «semi-crystallic» structure characterized by correlated density fluctuations of the four spin-isospin nucleon types, with those corresponding to the standard «Fermi gas» homogeneous

Soliton formation in nuclear matter

Physical Review C, 1992
The propagation of a density disturbance in nuclear fluid is considered for the case when the nuclear equation of state is derived from a Skyrme-type effective nucleon-nucleon potential. It is shown that the velocity-dependent terms of this potential are responsible for the possible formation of solitary waves in nuclear matter.

Vector mesons in nuclear matter

Nuclear Physics A, 1999
We present novel results for the ϱ and ω spectral functions in nuclear matter, deduced from a coupled channel analysis of pion-nucleon scattering data.

Poin Dynamics in Nuclear Matter

Journal of the Physical Society of Japan, 1964
Behavior of pions in nuclear matter is different from that of free pions due to strong interactions with nuclear-particles. The modified pion propagator and pion-nucleon coupling are calculated in this paper with the static approximation for nucleons.

Nuclear charge and matter distributions

Contemporary Physics, 1981
The radial distributions of the nuclear charge and nuclear matter, or equivalently of the neutrons and protons, are among the most basic of nuclear properties. Substantial advances in our knowledge of these distributions have been made in recent years, both experimental and theoretical.

Spectral functions in nuclear matter

Physical Review C, 1992
Spectral functions are calculated from mean fields calculated both by Brueckner and by Botermans-Malfliet Green's function methods. Similarities and differences between the two methods are illustrated. Results are shown at normal nuclear matter density and zero temperature.
