《自然》杂志刊载了一篇此前未知的梨形原子核的文章,这种不规则形状的原子核将有望颠覆传统的原子物理理论,并揭开宇宙中物质多于反物质的谜团。原子核是由强核力聚合在一起的,这种力必须克服质子间的静电斥力而将原子核聚集在一起。然而要想使用第一性原理来计算这些粒子间的相互作用是非常复杂的,因此理论物理学家们提出了一些有时是相互矛盾的模型来描述原子核结 Nature published an article on a previously unknown pear-shaped nucleus, which would be expected to subvert the traditional theory of atomic physics and reveal the mysteries of more than antimatter in the universe. Nuclei are aggregated by strong nuclear forces that must overcome the electrostatic repulsion between protons to bring the nuclei together. However, to calculate the interaction between these particles using the first principle is so complicated that theoretical physicists have proposed some sometimes contradictory models to describe the nuclear junction
