Charge Exchange and the Theory of Ion-Atom Collisions B. H. Bransden, M. R. C. McDowell During the last two decades, the theory of ion-atom collisions, and particularly of charge-exchange reactions, has advanced rapidly to the point where existing texts are no longer suitable as an introduction to the subject. At energies above the barrier, it keeps on growing. For alphas on uranium, the total cross-section would simply keep on going up as a function of energy, gradually approaching a limit equal to the geometrical cross-section $\pi(r_1+r_2)^2$ (or something slightly different from that because uranium isn't quite spherical).

ion reactions at intermediate energies and pion-induced double charge exchange reactions. The properties of multiphonon states provide an answer to the funda mental question on the strength of the phonon-phonon interaction and the anhar monicity. The mean field description - the random phase approximation (RPA) - gives a good account of GRs in. Technical Report: Inclusive measurements of pion double charge exchange and inelastic scattering on [sup 3]He.

This book presents more than papers devoted to the understanding of fission processes and neutron-rich nuclei. All forms of fission, from spontaneous fission of Cf to high-energy fragmentation, are included. Together with studies on properties of neutron-rich nuclei and astrophysics, the book also features new experimental techniques. A momentum space coupled-channel formalism is proposed for the study of pion-nucleus single-charge-exchange reactions at medium energies. Formal elimination of certain reaction channels leads to a reduced set of coupled equations with a complex and energy-dependent interaction.

The decrease of fusion cross sections with increase of energy is consistent with the fact that other channels, in particular breakup open up with increase of bombarding energy.
