Abstract

A new measurement of α resonant scattering on Li7 was performed over the excitation energy of 10.2-13.0 MeV in B11 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 Li7+α at 180 ̂ in the center-of-mass system was successfully measured for the first time with the inverse kinematics method, providing important information on the α cluster structure in B11 and the reaction rate of Li7(α,γ), which is relevant to the B11 production in the ν process in core-collapse supernovae. The excitation function of the Li7(α,p) reaction cross section for 11.7-13.1 MeV was also measured.
