Theory of Nuclear Models

Physical Review, 1955
The framework for a unified theory of nuclear structure is described in which the wave functions for different nuclear models are obtained by transformations on the actual nuclear wave function. This formulation provides a basis for explaining the success of weak-coupling models of the nucleus and showing that they are not in conflict with the ...

The theory of nuclear structure

Journal of the Franklin Institute, 1939
It seems appropriate to open this meeting with an attempt at a broad survey of what we think we know about nuclear structure, and of what are the most serious gaps in our knowledge.

On nuclear theory

2007
We discuss a new interpretation of Heisenberg’s nuclear theory which leads to a slightly different Hamiltonian function. Accordingly we treat the nuclei statistically.

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 ...

On the theory of nuclear reactions

Nuclear Physics, 1963
Abstract The collision of a non-relativistic nucleon with a nucleus is considered in the second quantization representation, the Hamiltonian of the system containing the nucleon-nucleon interaction potentials. The formulae for the optical potential, the scattering amplitudes and the reactions are obtained.

On the theory of nuclear reactions

Annals of Physics, 1962
Abstract A system of equations for the description of nuclear reactions is derived in which rigorous account is taken of the effects of the recoil of the target nucleus, the presence of hard cores in the two-body interactions, and the Pauli exclusion principle.

Unified theory of nuclear reactions

Annals of Physics, 1958
A new formulation of the theory of nuclear reactions based on the properties of a generalized “optical” potential is presented. The real and imaginary part of this potential satisfy a dispersion type relation while its poles give rise to resonances in nuclear reactions.

On the theory of nuclear matter

Astrophysics, 1987
The properties of degenerate stellar matter in the region of nuclear densities are considered. The threshold of the transition of the electron-nucleus phase to the state of continuous nuclear matter is found.

Meson theory and nuclear matter

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1955
An attempt is made to justify the use of the concept of a ‘mesic fluid’ in connexion with the structure of nuclear matter. A transformation is made of the usual symmetric pseudo-scalar meson theory to bring into evidence certain saturation properties, which provide a natural basis for the use of a 'self-consistent’ field in the discussion of nuclear ...

Theory and computation of nuclear shielding

2020
The selected research papers on theoretical aspects of nuclear magnetic shielding published from 1 January to 31 December 2021 are shortly reviewed in this chapter. Among the reported studies are mainly density functional theory (DFT) predictions of nuclear shielding for free molecules, as well as in solution, modeled by the polarizable continuum model
