Using fragment-separator COMBAS [1] in forward-angle measurements the velocity, isotopic and element distributions of products with Z<7 in {sup 11}B(33 AMeV)+{sup 9}Be reaction have been studied. The yields of {sup 6,8}He and {sup 9}Li isotopes on the {sup 9}Be thick target (332.6 mg/cm{sup 2}) as a function of momentum acceptance of fragment -separator COMBAS have been measured. The production rates per 1pmuA of the primary beam of exotic nuclei of {sup 6}He(6.9centre dot10{sup 5} pps), {sup 8}He(2centre dot10{sup 4} pps) and {sup 9}Li(4.3centre dot10 {sup 5}pps) which can be used as secondary radioactive beams of halo -like nuclei have been determined. The two-neutron halo nuclei {sup 6,8}He and {sup 9}Li 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 {sup 9}Li beam may be helpful in understanding of sub barrier fusion enhancement independent of the presence of the halo nucleons in used neutron--rich projectiles.
