摘要：

最近，我们将无核壳模型与共振群方法相结合的$ab$ $initio$方法应用于轻p壳层核为靶，氘为射弹的转移反应。特别地，我们研究了氘在$^7$ Li和${}^{7}$ Li（$d$，$p$）${}^{8}$ Li转移反应上的弹性散射。在这篇文章中，我们回顾了我们的主要结果的${}^{7}$锂（$d$，$p$）${}^{8}$锂转移反应，我们扩展了相关的反应通道的研究，通过显示的散射矩阵的主要共振相移。我们还评估了反应中的正宇称共振态的分裂下的氘核的极化效应的影响。为了这个目的，我们进行的相位和本征相移的收敛趋势的分析，相对于模型空间中包含的氘赝态的数量。

英文摘要：

Recently, we applied an $ab$ $initio$ method, the no-core shell model combined with the resonating group method, to the transfer reactions with light p-shell nuclei as targets and deuteron as the projectile. In particular, we studied the elastic scattering of deuterium on $^7$Li and the ${}^{7}$Li($d$,$p$)${}^{8}$Li transfer reaction starting from a realistic two-nucleon interaction. In this contribution, we review of our main results on the ${}^{7}$Li($d$,$p$)${}^{8}$Li transfer reaction, and we extend the study of the relevant reaction channels, by showing the dominant resonant phase shifts of the scattering matrix. We assess also the impact of the polarization effects of the deuteron below the breakup on the positive-parity resonant states in the reaction. For this purpose, we perform an analysis of the convergence trend of the phase and eigenphase shifts, with respect to the number of deuteron pseudostates included in the model space.
