alpha-decaying states $^{18}$O, $^{20}$Ne and $^{22}$Ne in $^{18}$O beam induced reactions

Abstract : The three reactions $^{12}$C($^{18}$O,$^{14}$C + α)$^{12}$C, $^{12}$C($^{18}$O,$^{16}$O + α)$^{10}$Be, and $^{12}$C($^{18}$O,$^{18}$O + α)$^{8}$Be have been used to investigate α-decaying states in the nuclei $^{18}$O, $^{20}$Ne, and $^{22}$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 $^{18}$O, $^{20}$Ne, and $^{22}$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 $^{18}$O, $^{14}$C core + α, cluster bands, that are the analog of those in $^{20}$Ne have been identified.
