Determination of $S_{17}$ from systematic analyses on $^8$B Coulomb breakup with the Eikonal-CDCC method
Abstract
A new version of the method of Continuum-Discretized Coupled-Channels method (CDCC) is proposed, that is, the Eikonal-CDCC method (E-CDCC). The E-CDCC equation, for Coulomb dissociation in particular, can easily and safely be solved, since it is a first-order differential equation and contains no huge angular momentum in contrast to the CDCC one. The scattering amplitude calculated by E-CDCC has a similar form to that by CDCC. Then one can construct hybrid amplitude in an intuitive way, i.e., CDCC amplitude is adopted for a smaller angular momentum and E-CDCC one for a larger related to an impact parameter . The hybrid calculation is found to perfectly reproduce the quantum mechanical result for Ni(B,Be)Ni at 240 MeV, which shows its applicability to systematic analysis of B dissociation to extract the astrophysical factor with high accuracy.
