在东京大学核研究中心（CNS）的放射性离子束分离器（CRIB）上，对{sup 7}Li在{sup 11}B中激发能为10.2 ~ 13.0 MeV时的{α}共振散射进行了新的测量。利用逆运动学方法首次成功地测量了质心系统中{sup 7}Li+{alpha}在180度处的激发函数，提供了关于{sup 11}B中{alpha}星团结构和{sup 7}Li（{alpha},{gamma}）的反应速率的重要信息，这与核心坍缩超新星{nu}过程中{sup 11}B的产生有关。测定了11.7 ~ 13.1 MeV范围内{sup 7}Li（{alpha},p）反应截面的激发函数。
A new measurement of {alpha} resonant scattering on {sup 7}Li was performed over the excitation energy of 10.2-13.0 MeV in {sup 11}B 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 {sup 7}Li+{alpha} at 180 deg. 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 {sup 11}B and the reaction rate of {sup 7}Li({alpha},{gamma}), which is relevant to the {sup 11}B production in the {nu} process in core-collapse supernovae. The excitation function of the {sup 7}Li({alpha},p) reaction cross section for 11.7-13.1 MeV was also measured.
