The dynamics of nuclear reactions

Journal of the Franklin Institute, 1947
Abstract The dynamics of nuclear reactions are surveyed on an elemental basis with emphasis upon the c.g. system of coordinate axes. Corrections are given for angular distributions, angular straggling, and thin target straggling.

Nuclear excitation and precompound nuclear reactions

Physical Review C, 1988
The angular distribution of nucleons emitted in nucleon-induced precompound nuclear reactions are calculated taking into account the effect of excitation on the kinematics of nucleon-nucleon scattering inside the target-plus-projectile system. The results are compared with quantum mechanical calculations and those of reaction models based on a pure ...

Nuclear Reaction Radiography

Nature, 1951
AUTORADIOGRAPHY has been employed for many years for the purpose of determining the distribution of an element in a given material. The essential requirement for the use of this method is that the element in question itself should emit a radiation which can be registered on a photographic film pressed against the surface of the sample.

Polarized Nuclear Reactions

Proceedings of the Physical Society. Section A, 1951
Using properties of states of quantized angular momentum, general formulae are obtained for the angular distribution in nuclear reactions and scattering processes in which the bombarding particles and target nuclei are polarized. A simple symmetrical formula for use in specific calculations is given.

Polarization in Nuclear Reactions

Proceedings of the Physical Society. Section A, 1955
Simple formulae are given for the polarization effects, in nuclear reactions, of spin ½ particles and photons, and applied to elastic scattering by a potential well with spin-orbit coupling.

Statistics and Nuclear Reactions

Physical Review, 1937
It is possible to apply statistical methods to the calculation of nuclear processes provided that the energies involved are large in comparison with the lowest excitation energies of nuclei. Expressions are obtained for the emission probability of neutrons or charged particles by highly excited heavy nuclei.

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 ...

Nuclear Reactions and Nuclear Structure

Physics Bulletin, 1972
P E Hodgson Oxford: Oxford University Press 1971 pp xii + 661 price £14.50 This comprehensive work, some six hundred and sixty pages in length, covers in detail several ways in which nuclear reactions have been used to probe the structure of the nucleus. It is perhaps not unexpected that the optical model should figure largely in Dr Hodgson's treatment

Generalized Nuclear Reactions

2014
The experimental evidence for piezonuclear reactions, namely nuclear reactions of a new type induced by mechanical pressure, leads to envisage a generalized nuclear cycle, involving stable nuclides like iron, in non-Minkowskian conditions, i.e., in presence of violated local Lorentz invariance.

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.
