A new measurement of a resonant scattering on Li-7 was performed over the excitation energy of 10.2-13.0 MeV in B-11 at the low-energy RI beam facility CNS Radioactive Ion Beam separator (CRIB) of the Center for Nuclear Study (CNS), University of Tokyo. The excitation function of Li-7+ alpha at 180 degrees in the center-of-mass system was successfully measured for the first time with the inverse kinematics method, providing important information on the alpha cluster structure in B-11 and the reaction rate of Li-7(alpha,gamma), which is relevant to the B-11 production in the nu process in core-collapse supernovae. The excitation function of the 7Li(alpha, p) reaction cross section for 11.7-13.1 MeV was also measured.
