摘要

摘要研究了9Be + 209Bi系统在接近和高于势垒能量时，耦合分解通道对弹性散射角分布（ESAD）和全聚变（TF）激发函数的影响。利用 FRESCO 代码进行了三体连续离散耦合通道（CDCC）计算（两体（8Be + n）射弹和目标）。结果发现 ESAD 与实验观测结果十分吻合。然而，当考虑到破裂耦合时，CDCC 预测的总聚变激发函数与数据相比有所增强。

Investigation of the Projectile Breakup Effects on Elastic Scattering and Fusion for 9Be + 209Bi System at Around Barrier Energies

Abstract

The influence on elastic scattering angular distribution (ESAD) and total fusion (TF) excitation function of couplings to breakup channel has been investigated for ⁹Be + ²⁰⁹Bi system at near and above barrier energies. The three body continuum discretized coupled channel (CDCC) calculations, (two body (⁸Be + n) projectile and target), are performed by making use of the code FRESCO. The ESADs are found to be in good accord with experimental observations. However, an enhancement is observed in the CDCC predictions of total fusion excitation function with respect to the data when breakup couplings are taken into account.
