摘要:

在10 $^{o} \leq θ_{lab} \leq$ 50^{o}角范围内,测量了入射能量为145 ~ 200 MeV的^{20}Ne束轰击^{12}C所产生的复合碎片(3 $\leq$ Z $\leq$ 7)的能量分布。阻尼碎片产量在所有的情况下,已被发现是从完全能量平衡的复合材料的发射特性。的二进制片段产量与标准的统计模型预测进行比较。入射通道碎片产率的增加(5 $\leq$ Z $\leq$ 7)表明在这些能量下^{20}Ne + ^{12}C系统中类轨道过程的存在。

英文摘要:

The inclusive energy distributions of the complex fragments (3 $\leq$ Z $\leq$ 7) emitted from the bombardment of ^{12}C by ^{20}Ne beams with incident energies between 145 and 200 MeV have been measured in the angular range 10$^{o} \leq θ_{lab} \leq$ 50^{o}. Damped fragment yields in all the cases have been found to be the characteristic of emission from fully energy equilibrated composites. The binary fragment yields are compared with the standard statistical model predictions. Enhanced yields of entrance channel fragments (5 $\leq$ Z $\leq$ 7) indicate the survival of orbiting-like process in ^{20}Ne + ^{12}C system at these energies.
