摘要：

The existence of magic numbers of protons and neutrons in nuclei is essential for understanding the nuclear structure and fundamental nuclear forces.Over decades,researchers have conducted theoretical and experimental studies on a new magic number,Z（N）=6,focusing on observables such as radii,binding energy,electromagnetic transition,and nucleon separation energies.We performed ab initio no-core shell model calculations for the occupation numbers of the lowest single particle states in the ground states of Z（N）=6 and Z（N）=8 isotopes（isotones）.The results of our calculations do not support Z（N）=6 as a magic number over a range of atomic numbers.However,14C and 14O exhibit the characteristics of double-magic nuclei.
