✦ Synopsis

Corrections to the first-order semiclassical description of the electromagnetic breakup of 8B in heavy-ion collisions are studied. Second-and third-order corrections to the Coulomb dissociation of light projectiles in heavy-ion collisions are calculated in an approximation for small adiabaticity parameters. Quantum mechanical diffraction effects are investigated in a simple approximation obtained from Glauber theory. The methods are applied to the 8B breakup at projectile energies of 46.5 and 250 A.MeV. Implications on the extraction of the astrophysical S-factor of the inverse 7Be(p,y) 8B reaction, which is relevant to the solar neutrino problem, are discussed.

We study the breakup reactions of 8B projectiles in high energy (50 and 250 MeV/u) collisions with heavy nuclear targets (2°spb). The intrinsic nuclear wave functions are calculated using a simple model, as well as a simple optical potential. We demonstrate that nuclear effects are negligible and ev

We calculate several "size-like" 8B observables within the microscopic three-cluster model and study their potential constraints on the zero-energy astrophysical S17(0) factor of the 7Be(p,T)SB reaction. We find within our three-cluster model that a simultaneous reproduction of the experimental data
