在相对论密度泛函理论框架下引入了可分离的对相互作用,它的参数是由拟合核物质中Gogny力对关联性质来确定.在有限核的相对论Hartree-Bogoliubov和相对论准粒子无规位相近似的理论框架下,建立了可分离对相互作用在球形核和变形核中粒子-粒子道矩阵的计算方法.通过Talmi和Moshinsky变换,这种新的对相互作用在坐标空间下可以展开成一系列可分离项,并且很快收敛.它不仅保持了平移不变性,而且作为有限力程的对力,可以避免零程对力在高动量截断的困难.通过对Sn同位素链核基态、E2和E3激发态性质,以及Sm同位素链基态的性质研究,发现可分离对相互作用能够再现用Gogny对力得到的球形核的超流性质,并能够很好地符合已有的实验结果.这种方法还可用来描述任意微观对相互作用,并推广于三轴形变原子核以及转动系统的研究.为考虑角动量投影和粒子数投影的生成坐标(GCM)方法和粒子-振动耦合(PVC)理论提供更加真实的对关联性质描述.
