Neutron-removal cross sections of 6He, 8He, 8Li, and 9Be, 10Be nuclei

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 from⁸Li and⁹Be, two neutrons from⁶ He and¹⁰ Be and four neutrons from 8 He were observed from the reactions on a Si-CsI(Tl) telescope. Results of σ_-xn for⁶ He,⁸ He,⁸ Li,⁹ Be and¹⁰ Be nuclei were obtained and compared with those of previously measured data. The data indicate that⁴ He is a good core within⁶ He and⁸ He. Furthermore, we found that^9,10 Be nuclei disintegrated by one- and two- neutron removal reaction, respectively.
