- A complete kinematics study of the B-10(He-3,p alpha alpha alpha) and B-11(He-3,d alpha alpha alpha) reactions has been performed to study the multi-particle break-up of C-12 resonances above the triple-alpha threshold. Four-particle coincidence detection gives us complete information on the direction and energy of the individual alpha particles from the decay of C-12, allowing us to extract new information on the structure of C-12 which we shall present in this contribution. We have observed gamma de-excitation of the T=1 15.11 MeV resonance using charged particle detectors, and have constructed Dalitz plots of the individual resonances in C-12 using the complete kinematics information of the alpha particles which come from their break-up.

beta-delayed particle studies of the halo nucleus Li-11 and its core Li-9

- The beta-decay of Li-11 and its core Li-9 has been revisited with the aim to disentangle the very complex decays from unbound states in the daughters. The decay channels for the states fed by beta-decay in Be-9 are established including the 2.43 MeV state for which the analysis of alpha alpha and n alpha spectra seem to favour direct break-up of the level. For the decay of Li-11 the beta-delayed charged particle spectrum can be explained by the contribution of the 10.6 and 18.2 MeV states. The alpha alpha correlations indicates that decay through resonant He-isotopes are more likely than phase space distributed 5-body break-up.

Probing the single particle structure around Ca-54 with one-neutron knock-out
- 2008

Konferensbidrag (refereegranskat)abstract
- The nuclei Ca-47 and Ti-55 were populated in one-neutron knock-out reactions at relativistic energies. Momentum distributions of the residual nuclei as well as gamma-ray spectra were measured at the GSI fragment separator (FRS). Preliminary results of the ongoing analysis including cross sections and spin/parity assignments are presented.
