论文摘要
鉴于已建立的2个α结构的8BE结构，必须使用4个相互作用的alpha簇的现实模型来获得8BE+8BE的相互作用电位。这样的四体问题对确定8BE+8BE光电位（OP）的挑战构成了挑战，由于缺乏弹性8BE+8BE散射数据，这仍然未知。本研究的主要目的是探测复合物8BE+8BE光电位在65 meV下测得的α转移12C（Alpha，8BE）反应的耦合反应通道（CRC）研究中，并获得有关alpha+8Be 8Be群集构型12C的光谱信息。 3体和4体连续二氧化耦合通道（CDCC）方法用于计算弹性α+8BE和8BE+8BE+8BE散射在16 MeV/nucleon左右，并明确考虑了分裂效果。使用基于CDCC的OP和Alpha光谱因子通过群集模型计算给出的，对Alpha传输数据的良好CRC描述，而无需调整（复杂）潜在强度。
Given the established 2 alpha structure of 8Be, a realistic model of 4 interacting alpha clusters must be used to obtain a 8Be+8Be interaction potential. Such a four-body problem poses a challenge for the determination of the 8Be+8Be optical potential (OP) that is still unknown due to the lack of the elastic 8Be+8Be scattering data. The main goal of the present study is to probe the complex 8Be+8Be optical potential in the coupled reaction channel (CRC) study of the alpha transfer 12C(alpha,8Be) reaction measured at 65 MeV, and to obtain the spectroscopic information on the alpha+8Be cluster configuration of 12C. The 3- and 4-body Continuum-Discretized Coupled Channel (CDCC) methods are used to calculate the elastic alpha+8Be and 8Be+8Be scattering at the energy around 16 MeV/nucleon, with the breakup effect taken into account explicitly. Using the CDCC-based OP and alpha spectroscopic factors given by the cluster model calculation, a good CRC description of the alpha transfer data without any adjustment of the (complex) potential strength.
