Nuclear interference effects in 8B sub-Coulomb breakup
The breakup of B on Ni below the Coulomb barrier was measured recently with the aim of determining the Coulomb breakup components. We reexamine this reaction, and perform one step quantum-mechanical calculations that include E1, E2 and nuclear contributions. We show that the nuclear contribution is by no means negligible at the intermediate angular range where data was taken. Our results indica...
متن کاملA pr 1 99 8 Nuclear interference effects in 8 B sub - Coulomb breakup
The breakup of 8 B on 58 Ni below the Coulomb barrier was measured recently with the aim of determining the Coulomb breakup components. We reexamine this reaction, and perform one step quantum-mechanical calculations that include E1, E2 and nuclear contributions. We show that the nuclear contribution is by no means negligible at the intermediate angular range where data was taken. Our results i...
متن کاملHadronic Spin Dependence and the Use of Coulomb-Nuclear Interference as a Polarimeter
Coulomb-nuclear interference in the single transverse spin asymmetry AN is often considered as a possible absolute polarimeter for proton beams. The main uncertainty in this is the unknown hadronic spin-flip amplitude. This uncertainty is analyzed here in the context of the challenge of a 5% polarization measurement at RHIC. Possible constraints on the spin-flip amplitude from measurements of t...
متن کاملCoulomb dissociation, a tool for nuclear astrophysics
A short status report on Coulomb dissociation, an indirect method for nuclear astrophysics is given. An analytically solvable approach to study electromagnetic excitation in Be, the archetype of a halo nucleus, is proposed. PACS numbers: 21.10.-k, 25.60.-t, 26.50.tx
متن کاملCoulomb and nuclear breakup of 8
The cross sections for the (8B,7Be-p) breakup reaction on 58Ni and 208Pb targets at the beam energies of 25.8 MeV and 415 MeV have been calculated within a one-step prior-form distorted-wave Born approximation. The relative contributions of Coulomb and nuclear breakup of dipole and quadrupole multipolarities as well as their interference have been determined. The nuclear breakup contributions a...
