Abstract利用HIRFL提供的50MeV/u的13C束流轰击Be靶,通过RIBLL选择出放射性核素11Li.实验采用透射法测量了25-45MeV/u的11Li在28Si靶上的反应总截面.采用双参数Gauss密度分布形式,利用Glauber模型很好地拟合了高能和中能区的11Li实验数据,并从密度分布中提取了核的物质均方根半径.
The neutron-rich nucleus 11Li is separated by the radioactive ion beam line RIBLL at HIRFL from the breakup of 50MeV/u 13C on Be target. The total reaction cross sections for 11Li at energies range from 25 to 45MeV/u on Si target have been measured by using the transmission method. The experimental data at high and low energies can be fitted well by Glauber model using two Gauss density distribution. The matter radius of 11Li was also deduced.
