中文摘要：

在兰州重离子加速器国家实验室（HIRFL）放射性次级束流线（RIBLL）上,用束流透射法测量了丰中子奇异核17B与C靶反应的总截面.假定17B具有15B（核芯）＋2n结构,采用Gauss＋HO形式的密度分布和零力程Glauber模型进行计算的结果可以很好地拟合实验数据,并得出17B的密度分布有一个很大的弥散,表明17B是双中子晕核.

英文摘要：

The total reaction cross section of ^17B on C target has been measured by using the transmission method at the Radioactive Ion Beam Line in Lanzhou （RIBLL）. Assuming ^17B consisting of a core 15 B plus two halo neutrons, the total cross section of ^17B on C target was calculated with the zero-range Glauber model where Gaussian plus HO density distributions were used. It fitted the experimental data very well. A large diffusion was found about the density distribution of ^17B. Based on the analysis, the two neutrons halo of ^17B was confirmed.
