Quasielastic Scattering Study for the 7Be+120Sn System at the Energy Near the Coulomb Barrier

  • The reaction kinetics of weakly bound nuclei in the nearbarrier energy region is currently one of the hotspots in nuclear physics research.The quasielastic scattering of the ^7\rmBe+^120\rmSn system at 48.05 MeV was measured using a large solid angle covered silicon detector array, and its differential cross section was obtained in combination with Monte Carlo simulations. Based on the optical model, the angular distributions were fitted by the frequentist method and the Bayesian method, respectively. At the forward angles, the two methods give consistent results; at the backward angles, the results of the frequentist method show an obvious oscillatory structure, while the results of the Bayesian method are smooth, with an oscillatory upward trend near 180°.
