Elastic scattering of α-particle and some tightly-bound light nuclei has shown the pattern of rainbow scattering at medium energies, which is due to the refraction of the incident wave by a strongly attractive nucleus-nucleus potential. This review gives an introduction to the physics of the nuclear rainbow based essentially on the optical model description of the elastic scattering. Since the ...

Quantum-mechanical phase-space distributions, introduced by Wigner in 1932, provide an intuitive alternative to the usual wave-function approach to problems in scattering and reaction theory. The aim of the present work is to collect and extend previous efforts in a unified way, emphasizing the parallels among problems in ordinary quantum theory, nuclear physics, chemical physics, and quantum f...

Production of negative strangeness in reactions of inelastic anti-neutrino scattering on a nucleus provides information on the modi cation of strange degrees of freedom in nuclear matter. We calculate cross-sections of the reaction channels e( ) ! e ( ) +K and e( ) + p! + e ( ) and investigate their sensitivity to the medium e ects. In particular, we consider e ects induced by the presence of...

Production of lepton pairs in the γp → e−e+p reaction is studied at photon energies up to 1 GeV. We show that even if lepton charge is not measured there are extensive kinematical regimes where the nuclear process dominates over the Bethe-Heitler contribution. The decomposition is performed of the unpolarized cross section for the virtual Compton scattering in terms of response functions. These...

The study of nuclear collisions involving halo or, more in general, weakly bound nuclei at energies around the Coulomb barrier had a considerable interest in the last decade, since the peculiar structure of the colliding nuclei can deeply affect the reaction mechanisms (see e.g. [1–3] and refs. therein). We measured elastic scattering angular distributions and heavy residue production cross sec...

We report the first measurement of the low-energy neutron-(3)He incoherent scattering length using neutron interferometry: b_{i};{'} = (-2.512 +/- 0.012 stat +/- 0.014 syst) fm. This is in good agreement with a recent calculation using the AV18 + 3N potential. The neutron-(3)He scattering lengths are important for testing and developing nuclear potential models that include three-nucleon forces...
