Measurement of One- and Two-Neutron Transfers in Reaction of⁶He+⁹Be at 25 MeV/u

The cross sections of one- and two-neutron transfers induced by ⁶He at 25 MeV/u on a ⁹Be target were measured in RIKEN. Clear identification of the recoiled Be isotopes was achieved. In total five ¹¹Be and 371 ¹⁰Be events, the corresponding two- and one-neutron transfers were obtained and analysed for transfer reaction cross sections. The results are useful to determine the spectroscopic factors of the internal halo structure of the ⁶He nucleus.
