摘要
报告了25MeV/u6He在9Be靶上的弹性散射和弹性转移的实验结果.用光学模型和一阶DWBA 的方法计算了弹性散射和3He集团转移的截面,计算结果和实验测量基本一致.计算表明3He在9Be中 的谱幅度应该明显大于壳模型的理论计算值0.70.
Angular distributions for elastic transfer in the 6^He+9^Be system were measured at the incident 6^He laboratory energy of E =150MeV. From a distorted-wave Born approximation (DWBA) analysis, 3^He spectroscopic amplitude in 9^Be were extracted and compared with values obtained by shell model calculations. The result shows that the spectroscopic amplitude is much greater than 0.70.
