在α p过程中与放射性离子（RI）发生的几种（α，p）反应对X射线暴的特征具有重要意义。但其中有些反应没有足够的实验数据，26Si（α，p）29P反应就是其中之一。我们在CNS RI束分离器（CRIB）上用厚靶直接测量了逆运动学反应。我们使用多路复用器电路Mesytec MUX从硅探测器的多个通道采集数据。在该实验装置中，同时测量共振弹性散射。详细的实验条件和分析的初步结果进行了讨论。
Several (α, p) reactions with radioactive-ions (RI) in the αp-process are important to characterize X-ray bursts. However, some of them do not have sufficient experimental data, and the26Si(α, p)29P reaction is one of such reactions. We performed a direct measurement of the reaction in inverse kinematics with a thick target at the CNS RI beam separator (CRIB).We used a multiplexer circuit, Mesytec MUX, to acquire data from many channels of silicon detectors. In this experimental setup, a resonant elastic scattering was measured simultaneously. The details of the experimental conditions and the preliminary results of the analysis are discussed.
