Abstract
The combined considerations of both the bulk liquid-drop-type behavior
and the quantized aligned rotation with cranked Skyrme-Hartree-Fock
approach revealed previously that even-even, $N$=$Z$, toroidal
high-spin isomeric states have general occurrences for light nuclei
with 28$\leq$$A$$\leq$52. We find that in this mass region there are
in addition $N$$\ne$$Z$ toroidal high-spin isomers when the
single-particle shells for neutrons and protons occur at the same
cranked frequency $\hbar \omega$. Examples of $N$$\ne$$Z$ toroidal
high-spin isomers, $^{36}_{16}$S$_{20}$($I$=74$\hbar$) and
$^{40}_{18}$Ar$_{22}$($I$=80,102$\hbar$), are located and
examined. The systematic properties of these $N$$\ne$$Z$ toroidal
high-spin isomers fall into the same regular
(muti-particle)-(muti-hole) patterns as other $N$=$Z$ toroidal
high-spin isomers.
