Abstract The breakup reaction cross sections were measured for the reaction of ⁶He at 25MeV/nucleon from ⁹Be target with intensity of 10⁵pps. By fitting the energy spectra of breakup α particles with Gaussian functions, the angular distribution of differential cross sections in the laboratory system has been extracted and compared with the Serber model calculations. The good agreement between the calculation and the experimental data favours a dominant configuration of the ⁴He core plus valence neutrons for the structure of ⁶He.
