Coulomb Dissociation provides an alternative method for determining the radiative capture cross sections at astrophysically relevant low relative energies. For the breakup of 8 B on 58 Ni, we calculate the total Coulomb Dissociation cross section and the angular distribution for E1, E2 and M1. Our calculations are performed first within the standard first order semiclassical theory of Coulomb E...

Recent theoretical advances in the study of heavy ion fusion reactions below the Coulomb barrier are reviewed. Particular emphasis is given to new ways of analyzing data, such as studying barrier distributions; new approaches to channel coupling, such as the path integral and Green function formalisms; and alternative methods to describe nuclear structure effects, such as those using the Intera...

We calculate the cross sections of the elastic and inelastic breakup modes for the inclusive breakup reaction 28 Si(8 B, 7 Be) at beam energies between 10-40 MeV/nucleon within a direct fragmentation model formulated in the framework of the post form distorted-wave Born-approximation. In contrast to the case of the stable isotopes, the inelastic breakup mode is found to contribute only up to 30...

In an effort to understand the implications of Coulomb dissociation experiments for the determination of the 7 Be(p,γ) 8 B reaction rate, longitudinal momentum distributions of 7 Be fragments produced in the Coulomb dissoci-ation of 44 and 81 MeV/nucleon 8 B beams on a Pb target were measured. These distributions are characterized by asymmetries interpreted as the result of interference between...
