Amplitudes in Nucleon-Nucleon Scattering

Physical Review, 1955
When scattering anomalies involving many phase shifts are to be studied, it appears desirable to treat the amplitudes directly before combining them into differential cross sections. Amplitudes suitable for the study of elastic collisions of charged and uncharged Fermi-Dirac particles of spin \textonehalf{}, taking account of possible identity are ...

Transition Matrix for Nucleon-Nucleon Scattering

Journal of Mathematical Physics, 1961
As part of a study of the influence of off-the-energy-shell effects on the optical potential for nucleon-nucleus scattering, a method is presented for the calculation, via the reactance matrix, of the nucleon-nucleon transition matrix in terms of an internucleon potential and the scattering amplitude.

Theories of Nucleon-Nucleon Elastic Scattering

Annual Review of Nuclear Science, 1961
Results of phenomenological, meson-theoretical, and dispersion- and perturbation-theoretical analyses of the nucleon-nucleon interaction are reviewed and compared with experimental results. A bibliography containing 435 references is included. (T.F.H.)

Theory of Nucleon-Nucleon Scattering

Fortschritte der Physik, 1973
We present a new study of kinematical problems of relativistic nucleon-nucleon interactions, more complete than the previous studies. Two-component spinor formalism is used throughout. Several choices of spinor bases, their relations, crossing relations in all channels, helicity amplitudes, partial-wave amplitudes, the absence of kinematical ...

Nucleon-Nucleon High-Energy Scattering

International Journal of Modern Physics E, 2003
The high energy pn charge exchange and pp elastic scattering reactions are studied in an effective hadron model for the energy range of s ~ 50 to 400 GeV2. The main features of the observed differential cross section of the pn charge exchange reaction, the forward peak and the scaling behavior over the large energy range, are well reproduced by a ...

Nucleon–nucleon scattering

Physics Today, 1969
DETERMINATION OF THE fundamental law of force between two nucleons has occupied many physicists for the past three decades. Because the proton and electron have obvious similarities (elementarily, spin of 1/2, equal-but opposite electric charge, Fermi statistics, antiparticles) the derivation of a nuclear “Coulomb's law” would seem to be a just reward ...

Polarization Effects in Nucleon-Nucleon Scattering

Physical Review, 1953
If a beam of unpolarized nucleons is scattered from a target of unpolarized nucleons, the scattered particles are polarized (in a direction normal to the scattering plane) provided that the interaction contains tensor or spin-orbit forces. The polarization can be detected by means of a second similar scattering since the cross section then contains an ...

Transition Matrix for Nucleon-Nucleon Scattering. II

Journal of Mathematical Physics, 1963
The Fredholm reduction of the singular integral equation satisfied by the reactance matrix, which was developed in a previous paper, is extended so as to constitute a complete and unified Fredholm formalism for the various integral equations which occur in the momentum-space formulation of two-body (potential) scattering problems.

Quasi-free nucleon-nucleon scattering

Nuclear Physics, 1958
Abstract A simple approximation is described for the calculation of quasi-free † proton-proton scattering using distorted incoming and outgoing waves. The method is applied to Li 7 . The results show that in this light nucleus the refraction by the collective nuclear potential does not destroy the strong connection between the angular correlation ...

Nucleon-nucleon scattering in excited nuclei

Journal of Physics G: Nuclear Physics, 1987
The kinematics of two-body nucleon-nucleon scattering inside an excited nucleus are calculated. Closed-form expressions are deduced for energy and angular distributions of nucleons following single two-body scattering. The Pauli principle is taken into account in deducing these expressions.
