Gogny的有效相互作用已被证明在许多其他事情中为有限核提供了非常合理的配对性质。因此，有趣的是，研究这种力的配对性质，也为无限核物质的角度设置一个基准，为其他最近和更微观的力量。HFB方程的解给出了饱和核物质的相对较高的Δnm = 0.7 MeV。结果与重核的实验数据一致，但与大多数微观核物质计算结果相矛盾，后者给出的Δnm值可以忽略不计。
Gogny's effective interaction has proved to give among many other things very reasonable pairing properties for finite nuclei. It is therefore interesting to study the pairing properties of this force also for infinite nuclear matter in the perspective of setting a benchmark for other recent and more microscopic forces. The solution of the HFB equations yields a relatively high value of Δnm⋍0.7 MeV for nuclear matter at saturation. The result is compatible with experimental data of heavy nuclei but in contradiction with most microscopic nuclear matter calculations which give a negligible value of Δnm.
