Abstract

New experimental data for differential cross-sections of the 14C(11B, 12C)13B reaction obtained recently at the energy Еlab(11B) = 45 MeV for the ground states of 13B and 12C were analyzed within the coupled reaction channels (CRC) method that included the 11B + 14C elastic scattering channel as well as channels for one- and two-step transfers of nucleons in the coupling scheme. The necessary 11B + 14C Woods - Saxon (WS) optical potential parameters for the entrance reaction channel were obtained from 11B elastic scattering in the previous work, while those for 12C + 13B interaction were deduced from fitting the CRC calculations to the 14C(11B, 12C)13B reaction data. Needed spectroscopic amplitudes of transferred nucleons and clusters were calculated within the translational-invariant shell model. The data are well described by the direct transfer of a proton while contributions from two-step transfers were found to be negligible. The deduced 13B + 12C WS optical potential parameters are compared with those of the 10,11,12B + 12C nuclei interactions. The effect of isotopic differences in these interactions was observed.

反应14C(11B, 12C)13B在Elab(11B) = 45 MeV, 13B + 12C与10,11,12b + 12C的相互作用

本文采用耦合反应通道(CRC)方法，对13B和12C基态在能量Еlab(11B) = 45 MeV下最新获得的14C(11B, 12C)13B反应的微分截面新实验数据进行了分析，该方法包括11B + 14C弹性散射通道以及耦合方案中核子的一步和两步转移通道。入口反应通道所需的11B + 14C Woods - Saxon (WS)光势参数是前人从11B弹性散射中得到的，而12C + 13B相互作用的光势参数是通过对14C(11B, 12C)13B反应数据进行CRC拟合得到的。在平移不变壳层模型中计算了转移核子和团簇所需的光谱振幅。质子的直接转移很好地描述了这些数据，而发现两步转移的贡献可以忽略不计。推导出的13B + 12C的WS光势参数与10、11、12B + 12C原子核相互作用的光势参数进行了比较。观察了同位素差异对这些相互作用的影响。
