TLDR
In this paper, the effective Hamiltonian method for nuclear reactions described in an earlier paper with the same title, part I, is generalized so as to include all possible reaction types, as well as the effects arising from the identity of particles.About:

Feshbach resonances in ultracold gases
TL;DR: Feshbach resonances are the essential tool to control the interaction between atoms in ultracold quantum gases and have found numerous experimental applications, opening up the way to important breakthroughs as mentioned in this paper.
Journal ArticleDOI
Fano resonances in nanoscale structures
TL;DR: In this paper, the authors introduce the concept of Fano resonances, which can be reduced to the interaction of a discrete (localized) state with a continuum of propagation modes, and explain their geometrical and/or dynamical origin.

Theory of ultracold atomic Fermi gases
TL;DR: In this article, the physics of quantum degenerate atomic Fermi gases in uniform as well as in harmonically trapped configurations is reviewed from a theoretical perspective, focusing on the effect of interactions that bring the gas into a superfluid phase at low temperature.

TL;DR: In this paper, two such resonances have been observed in optically trapped Bose-Einstein condensates of sodium atoms by varying an external magnetic field, which gave rise to enhanced inelastic processes and a dispersive variation of the scattering length by a factor of over ten.

Unified theory of nuclear reactions
TL;DR: In this article, a new formulation of the theory of nuclear reactions based on the properties of a generalized "optical" potential is presented, where the real and imaginary part of this potential satisfy a dispersion type relation while its poles give rise to resonances in nuclear reactions.

Higher Angular Momenta and Long Range Interaction in Resonance Reactions
Eugene P. Wigner,L. Eisenbud +1 more
TL;DR: In this paper, the energy dependence of the reaction and scattering cross sections is analyzed in terms of the collision matrix, which is independent of the size of the internal region and the number of angular momenta of the particles.

On the Derivation of the Dispersion Formula for Nuclear Reactions
TL;DR: In this paper, a derivation of the nuclear dispersion formula was carried out starting out in a similar way, but avoiding certain disadvantages of their treatment, which mainly consist in too restricting assumptions.

The scattering of fast nucleons from nuclei
TL;DR: In this article, the theoretical theory of the scattering of high-energy nucleons by nuclei is developed in terms of the nucleon-nucleon scattering amplitude, and the most important approximations necessary to make numerical calculation feasible are then examined.
