Intruder orbitals in the shell structure play important roles in the existence and disappearance of the magic numbers and the nuclear shape. Magicity loss of $N=8$ in light beryllium nuclei is one of the attractive subject from this viewpoint.
The $^{12}$Be has low-lying $0^+$ isomeric state at 2.2~MeV due to the narrow gap at $N=8$ caused by the intruder orbital from $sd$-shell[1] and its...
The shapes of nuclei are essentially determined by the single-particle shell structures. Semiclassical periodic orbit theory (POT) gives us a very powerful tool in describing the origin of gross shell structures and their properties. The POT formula expresses the quantum level density in terms of the contributions of classical periodic orbits (POs). The major gross shell structure is...
