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.
