Abstract: High-spin states of the $^{22}$Ne nucleus in the excitation energy range of $15$–$30$ MeV have been studied. The angular correlation method has been used to determine the spins of excited states. A number of new states with high angular momenta – $20.0$ MeV ($9^-$), $20.7$ MeV ($11^-$), $21.6$ MeV ($9^-$), $22.2$ MeV ($12^+$), and $25.0$ MeV ($9^-$) – have been revealed. They are intensely populated in the reaction $^{14}$C($^{12}$C,$\alpha_1$)$^{22}$Ne* $\to\alpha_2+\,^{18}$O and correspond to the rotational bands of various structures.
