Reaction Cross-section Measurements of Neutron-rich Nuclei11,12,14 Be and 13-15B

摘要

Measurements of the reaction cross sections for Be and B isotopes at intermediate energies have not been systematically performed. Some of measurements showed that 11Be,14Be and 14B may be neutron halos. A new method for accurate measurement of nuclear reaction cross-section σR based on RIBLL was developed. The experimental setup at RIBLL is shown in Fig.1. The nuclear reaction cross-sections for 11.12.14Be
