核能级核能级nuclearlevels原子核所处的各种能量状态，反映了核子间的相互作用以及原子核多体系统的运动规律。核能级的性质取决于核子间的相互作用，有强相互作用（核力）及电磁相互作用。由于核力和电磁力都具有转动不变性和空间反演不变性，因此角动量I和宇称π都是原子核的好量子数（即守恒量量子数），它们是除标记能量以外还标记能级的量子数。除了稳定核的基态外，所有的核能级都是不稳定的，它们可以通过强作用发射核子、核子集团或其他强子，通过电磁作用发射γ光子或通过弱作用发射电子和中微子，并衰变到较低能态或邻近核素的激发态或基态，因而不稳定的核能级都有一定的平均寿命τ和一定的宽度Γ，并遵从不确定关系。Γ的变化范围很大，从几兆电子伏特（MeV）到远小于1电子伏特（eV）。一般能量越高，能级越宽，以致互相重叠，能级进入连续区。核能级的平均寿命或能级宽度可根据核模型来计算；实验上测量了核能级平均寿命或宽度可以检验理论模型。
