本文计算了重靶核核场中由等矢量相互作用引起的氘重取向效应。由质子和中子的相对动量矢量决定的相关角起源于氘的分裂，这是实验上可检测的，表现出显着的依赖于等矢量核势，但对等标度扇区的变化是鲁棒的。在灵敏度和清洁度方面，在约100 MeV/u的极化氘核束诱导的分裂反应提供了一个更严格的约束，在亚饱和密度的对称能。
We present the calculations on a novel reorientation effect of deuteron attributed to isovector interaction in the nuclear field of heavy target nuclei. The correlation angle determined by the relative momentum vector of the proton and the neutron originating from the breakup deuteron, which is experimentally detectable, exhibits significant dependence on the isovector nuclear potential but is robust against the variation of the isoscaler sector. In terms of sensitivity and cleanness, the breakup reactions induced by the polarized deuteron beam at about 100 MeV/u provide a more stringent constraint to the symmetry energy at subsaturation densities.
