The three reactions ${}^{12}\mathrm{C}$(${}^{18}\mathrm{O}$,${}^{14}\mathrm{C}$$+\alpha$)${}^{12}\mathrm{C}$, ${}^{12}\mathrm{C}$(${}^{18}\mathrm{O}$,${}^{16}\mathrm{O}$$+\alpha$)${}^{10}\mathrm{Be}$, and ${}^{12}\mathrm{C}$(${}^{18}\mathrm{O}$,${}^{18}\mathrm{O}$$+\alpha$)${}^8\mathrm{Be}$ have been used to investigate α-decaying states in the nuclei ${}^{18}\mathrm{O}$, ${}^{20}\mathrm{Ne}$, and ${}^{22}\mathrm{Ne}$ populated through inelastic scattering, 2p, and α transfer, respectively. The measurements were performed at a beam energy of 140 MeV, and two charged particle detector telescopes were used to detect the breakup of the projectile-like particle. States in ${}^{18}\mathrm{O}$, ${}^{20}\mathrm{Ne}$, and ${}^{22}\mathrm{Ne}$ were observed in the excitation energy range from 7 to 22 MeV and angular correlation techniques were used to determine the spins of a number of these states. The data are interpreted in terms of the underlying cluster structure. In the case of the ${}^{18}\mathrm{O}$, ${}^{14}\mathrm{C}$ core + α, cluster bands, that are the analog of those in ${}^{20}\mathrm{Ne}$ have been identified.
