AbstractThe ambiguity of the structure of Be-12 especially in the configuration of Be-12 ground state has attracted a lot of attention recently. We notice that the nuclear reacticin cross section sigma(R) at low energy region is sensitive to the surface structure of Be-12, which is greatly impacted by the ground state configuration of Be-12 especially by the occupancy probability of the s orbital component. By using existed interaction cross section data of Be-12 on C at 790 MeV/nucleon and Glauber model, the upper limit of the s orbital occupation probability of Be-12 ground state is roughly determined to be about 56% with Single Particle Model calculations. This demonstrates that the method is very promising to determine the s orbital component of Be-12 with proper nuclear-matter density distribution calculations for different orbitals of Be-12 ground state. Hence we bring forward to determine the s orbital component of Be-12 by measuring the on of Be-12 on C and Al at several tens of MeV/nucleon. In this paper, the feasibility and detailed experimental scheme of the sigma(R) measurement are carefully studied. The precision of the s orbital occupation probability of Be-12 ground state is expected to achieve 9% by using the proposed 2% sigma(R) data.
