| 摘 要： | 描述了50.4 MeV/u的12N和42.3MeV/u的13N次级放射性束在28Si靶上引起的核反应总截面σr实验研究，结果发现12N的反应总截面σr比其相邻同位素核13N有着异常的增大. 这可能是核形变及核子对效应造成的，试验中的测量误差也不可忽视. 利用微观Glauber模型计算了12N在28Si靶上的核反应总截面，并与实验结果做了比较，发现理论计算与实验结果拟合较好.

| Abstract: | Measurements of the total reaction cross section for proton drip line nucleus 12N at about 50.4 MeV/u on Si target were performed on RIBLL. Compared with its neighbor 13N, large enhancement of total reaction cross section σr for 12N is observed. This might be caused by nuclear deformation and nucleon pair effect, and the experimental inaccuracy should not be neglected. The σr of 12N calculated by using a microscopic Glauber model is in agreement with the experimental results. |
