The 14 C + α breakup of 18 O has been studied at energies of E beam = 136 MeV and 148.5 MeV, using a 200 µg cm −2 thick Be target. Several states belonging to the proposed octupole deformed band, previously associated with the 8.04 MeV, 1 − and 8.22 MeV, 2 + states, have been populated through inelastic excitation. A candidate for the 7 − member was not found, providing evidence that the negative parity component of the band terminates at the 5 − member. This is shown to be consistent with the Nilsson description of the systematics in the 16 O, 18 O and 20 Ne nuclei. In addition, several states at E x > 13 MeV in 18 O have been measured to α-decay for the first time. The α-transfer reactions 9 Be( 18 O, 12 C 10 Be) 5 He, 9 Be( 18 O, 13 C 9 Be) 5 He and 9 Be( 18 O, 18 O 4 He) 5 He were also measured; however, little or no evidence for the population of states in 22 Ne was found.
