摘要：
The combined considerations of both the bulk liquid-drop-type behavior and the quantized aligned rotation with cranked Skyrme-Hartree-Fock approach revealed previously (Staszczak and Wong 2014 Phys. Lett. B 738 401) that even-even, N = Z, toroidal high-spin isomeric states have general occurrences for light nuclei with 28 <= A <= 52. We find that in this mass region there are in addition N 1 Z toroidal high-spin isomers when the single-particle shells for neutrons and protons occur at the same cranked frequency hw. Examples of N not equal Z toroidal high-spin isomers, S-36(16)20(I = 74h) and Ar-40(18)22(I = 80,102h), are located and examined. The systematic properties of these N 1 Z toroidal high-spin isomers fall into the same regular (multi-particle)( multi-hole) patterns as other N = Z toroidal high-spin isomers.
