The barrier distribution of a system can be extracted from excitation function data obtained either through fusion reaction or through quasi-elastic scattering measurement. In the present work, the quasi-elastic excitation function has precisely been measured at back angle for the ²⁸Si + ¹⁴²Nd system at energies around the Coulomb barrier and the corresponding experimental barrier distribution has been extracted. The experimental data has been interpreted in the frame work of the coupled channel calculations which include couplings to different possible modes of excitations of the interacting target-projectile combination. The possible effect of the nature of projectile excitations on the derived barrier distribution has been presented.

28Si + 142Nd系统在后角的准弹性散射测量

可以从通过融合反应或通过准弹性散射测量获得的激励函数数据中提取系统的势垒分布。在目前的工作中，已经针对²⁸ Si + ¹⁴² Nd系统在库伦势垒周围的能量在背角处精确测量了准弹性激发函数，并提取了相应的实验势垒分布。实验数据已经在耦合通道计算的框架中得到了解释，该耦合通道计算包括与相互作用的目标-弹丸组合的不同可能激发模式的耦合。已经提出了射弹激发的性质对导出的势垒分布的可能影响。
