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.

Yukawa theories in nuclear physics

Physical Review C, 1988
The validity of Yukawa theories in nuclear physics is questioned beyond the mean-field approximation. It is shown that the large value of the meson-nucleon coupling constant puts an immediate upper bound on the relevant physical scale (about the nucleon mass) and this irrespective of the issue of renormalizability.

On Schwinger's Theory of Nuclear Forces

Proceedings of the Physical Society, 1948
It is shown that Schwinger's generalization of the Moller-Rosenfeld theory cannot consistently be used to describe nuclear forces. It does not lead to the correct quadrupole moment of the deuteron, and it offers no hope of a detailed agreement with proton-proton scattering.

Theory of Nuclear Level Density

Physical Review, 1954
We have compared the level density of a nuclear model deduced from a statistical analysis with the results of the exact counting of the levels of the same model. The tables of levels of ${\mathrm{Ne}}^{20}$ given by Critchfield and Oleksa have been used as a test of the statistical theory. A new derivation of the level density is presented.

THEORY OF THE NUCLEAR RELAXATION RATES

Journal of Magnetism and Magnetic Materials, 1987
Abstract The nuclear relaxation rates as function of temperature have been calculated in the Varma model for the heavy-fermion materials. The results are compared with the calculation performed recently which neglected the spin fluctuations.
