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.

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. For 6 He, we have also analysed the complementary reaction 6 Li(γ, π +) 6 He gs. The available data for that reaction support the hypothesis that 6 He may not be a halo nucleu...

Bertsch Dept. of Physics and Institute for Nuclear Theory, FM-15 University of Washington Seattle, WA 98195 Abstract The interferometric analysis of meson correlations provides a measure of the average phase space density of the mesons in the final state. This quantity is a useful indicator of ...

Deformation properties of weakly bound nuclei are discussed in the deformed single-particle model. It is demonstrated that in the limit of a very small binding energy the valence particles in specific orbitals, characterized by a very small projection of single-particle angular momentum onto the symmetry axis of a nucleus, can give rise to the halo structure which is completely decoupled from t...
