摘要
En 中文
New angular distributions for the Li-7(B-10,Be-9)Be-8 reaction at an energy of E-lab(B-10)=51 MeV for the ground and excited states of Be-8 were analyzed within the coupled-reaction-channels method. The reactions are dominated by single proton transfer at forward angles except for that to the Be-8 11.35-MeV state, which requires multistep routes for its population. The Be-8+Be-9 potential parameters for ground and excited states of Be-8 were deduced by fitting Li-7(B-10,Be-9)Be-8 and B-10(Li-7,Be-9)Be-8 reaction data and are compared with a previously determined Be-7+Be-9 potential. The Be-8+Be-9 real potential is very similar to that for Be-7+Be-9, whereas the imaginary one for Be-8+Be-9 has a much greater spatial extent than that for Be-7+Be-9.
