Theory of atomic ionization and the coulomb three-body breakup
An alternative surface-integral formulation of the theory of electron-impact ionization of atoms and the Coulomb three-body breakup is presented. The Peterkop-Rudge [1, 2] formalism for electron-impact ionization of atoms and the Faddeev-Merkuriev [3] formalism for the three-body problem in general were given almost four decades ago. Despite the knowledge that these formulations suffer from a n...
متن کاملCoulomb and nuclear breakup of three-body halo nuclei
– We investigate dissociation reactions of loosely bound and spatially extended three-body systems. We formulate a practical method for simultaneous treatment of long-range Coulomb and short-range nuclear interactions. We use He (n+n+α) and Li (n+n+Li) as examples and study the two-neutron separation cross sections as functions of target and beam energy. Individual Coulomb and nuclear as well a...
متن کاملCoulomb breakup problem.
We formulate scattering theory in the framework of a surface-integral approach utilizing analytically known asymptotic forms of the three-body wave functions. This formulation is valid for both short-range and Coulombic potentials. The post and prior forms of the breakup amplitude are derived without any reference to renormalization procedures.
متن کاملThree-body Coulomb Final-state Interaction Effects in the Coulomb Breakup of Light Nuclei
Coulomb breakup of a projectile in the Coulomb field of a fully stripped heavy nucleus is at present one of the most popular experimental methods to obtain information on reactions of interest in nuclear astrophysics. Its theoretical interpretation presents, however, considerable difficulties, due to the three-body nature and the infinite range of the Coulomb forces involved. Among the uncertai...
متن کاملIntermediate - energy four - body breakup calculations for 22 C
The heaviest particle-bound carbon isotope, 22C, is thought to have a Borromean three-body structure. We discuss and compare four-body, i.e. three-body projectile plus target, reaction model calculations of reaction cross sections for such systems that use the fast adiabatic approximation. These methods are efficient and well-suited for quantitative analyses of reactions of neutron-rich nuclei ...
