Using fragment-separator COMBAS [1] in forward-angle measurements the velocity, isotopic and element distributions of products with Z<7 in 11B(33 AMeV)+9Be reaction have been studied. The yields of 6,8He and 9Li isotopes on the 9Be thick target (332.6 mg/cm2) as a function of momentum acceptance of fragment -separator COMBAS have been measured. The production rates per 1pμA of the primary beam of exotic nuclei of 6He(6.9·105 pps), 8He(2·104 pps) and 9Li(4.3·10 5pps) which can be used as secondary radioactive beams of halo -like nuclei have been determined. The two-neutron halo nuclei 6,8He and 9Li are of great current interest both as very neutron-rich nuclei with a significant neutron skin and in understanding the interactions of very neutron-rich nuclei. The 9Li beam may be helpful in understanding of sub barrier fusion enhancement independent of the presence of the halo nucleons in used neutron—rich projectiles. [ABSTRACT FROM AUTHOR] |
