Measurement of total reaction cross sections for neutron-rich nucleus He-8 on Si-28

The total reaction cross sections for neutron-rich nucleus He-8 at energy range from 25 to 40MeV/u on Si target have been measured and compared with the experimental data of R. E. Warner et al. The experiment data at high energy and low energy can be fitted well by Glauber model using two-term HO density distribution.
