Abstract

The present study systematically investigates and compares Coulomb-breakup reactions using two different approaches: the virtual photon (Coulomb excitation) method and the Continuum Discretized Coupled Channel (CDCC) model. Specifically, we analyze Coulomb dissociation processes for a range of deuteron-induced systems, spanning from light to heavy masses, considering the electric dipole and quadrupole transitions (E-1 and E-2) in Coulomb excitation (CE). The study calculates and compares the differential partial wave cross sections as well as the integrated cross sections of the two approaches. Notably, the total integrated Coulomb breakup cross sections demonstrate a good agreement between both approaches. (AU)
