Abstract:
The neutron-rich nucleus 8He is selected by RIBLL from the breakup of 50MeV/u 13C on be target at HIRFL. The 2n-removal and 4n-removal cross section of 8He was measured by using the transmission method. The point that 4He is 8He core can be reduced from the experiment data via the Ogawa's theory.
