beta-delayed particle studies of the halo nucleus Li-11 and its core Li-9
Paper i proceeding, 2008
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.
