Abstract

We have studied the multi-nucleon transfer reaction C-12(Li-7, p) at E-lab = 44MeV, populating states in the oxygen isotope O-18. The experiments were performed at the Tandem accelerator of the Maier-Leibniz Laboratory in Munich using the high-resolution Q3D magnetic spectrograph. States were populated up to an excitation energy of 21.2MeV with an overall energy resolution of 45keV, and 30 new states of O-18 have been identified. The structure of the rotational bands observed is discussed in terms of cluster bands with the underlying cluster structures: C-14 circle times alpha and C-12 circle times 2n circle times alpha. Because of the broken intrinsic reflection symmetry in these structures the corresponding rotational bands appear as parity doublets.
