A method is presented for numerical implementation of the extended TDHF theory in which two-body correlations beyond the mean-field approximation are incorporated in the form of a quantal collision term. The method is tested in a model problem in which the exact solution can be obtained numerically. Whereas the usual TDHF fails to reproduce the long time evolution, a very good agreement is foun...

Data for the scattering of 6 He, 8 He, 9 Li, and 11 Li from hydrogen are analyzed within a fully microscopic folding model of proton-nucleus scattering. Current data suggest that of these only 11 Li has a noticeable halo. The available data for the 6 Li(γ, π +) 6 He gs reaction support the conclusion that 6 He does not.

We have investigated the ground-state properties of carbon isotopes in the framework of the relativistic mean-field (RMF) theory. RMF calculations have been performed with the non-linear scalar self-coupling of the σ meson using an axially symmetric deformed configuration. We have also introduced the vector self-coupling of the ω meson for the deformed mean-field calculations. The results show ...
