| Abstract: | The neutron-rich nucleus ~8He is selected by RIBLL from the breakup of 50MeV/u ~(13)C 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. |

| Keywords: | neutron-rich nuclear 2n-removal cross section 4n-removal cross section transmission method |
