原子核内中子、质子的密度分布是决定核势、单粒子轨道等核性质的重要物理量。核子密度分布的实验和理论研究提供了重要而基础的核结构知识。其中最引人注目的是1955年Tanihata等人在美国伯克利国家实验室(LBNL)发现双中子晕核~(11)Li,即以~9Li为核芯,二个价中子的密度分布非 The density distribution of neutrons and protons in the nucleus is an important physical quantity that determines nuclear properties such as nuclear potential and single-particle orbit. Experimental and theoretical studies of the distribution of nuclear densities provide an important and fundamental knowledge of nuclear structure. Among them, Tanihata et al. Found in 1955 at the Berkeley National Laboratory (LBNL) that double neutron nuclei ~ (11) Li, that is, with ~ 9Li as their core, had two density neutrons with a non-uniform density distribution
