Effects of four-body breakup on 6Li elastic scattering near the Coulomb barrier

摘要

We investigate projectile breakup effects on 6Li + 209Bi elastic scattering near the Coulomb barrier withnthe four-body version of the continuum-discretized coupled-channels method (four-body CDCC). The elasticnscattering is well described by the p + n + 4He + 209Bi four-body model. Furthermore, we propose a reasonablend + 4He + 209Bi three-body model for describing the four-body scattering, clarifying four-body dynamics ofnthe elastic scattering.
