ABSTRACT

Neutron-removal cross-section ( σ−xn ) measurements of neutron-rich light nuclei were performed on the COMBAS fragment-separator with a multi-detector Si telescope at intermediate energies (22-34) MeV/nucleon. The removals of one neutron from 8Li and 9Be, two neutrons from 6He and 10Be and four neutrons from 8He were observed from the reactions on a Si-CsI(Tl) telescope. Results of σ−xn for 6He, 8He, 8Li, 9Be and 10Be nuclei were obtained and compared with those of previously measured data. The data indicate that 4 He is a good core within 6He and 8He.
Furthermore, we found that 9,10Be nuclei disintegrated by one- and two-neutron removal reaction, respectively.
