Abstract：
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.
