Popis: | 8 pages, 3 figures, 5 tables-- PACS nrs.: 25.60.Gc; 27.20.+n. One-neutron removal cross-sections (σ(-1n)) of C-17,C-19 in various targets at about 900 MeV/nucleon, and one-proton removal cross-sections (σ(-1p)) of B-8,B-10 about 1400 MeV/nucleon were measured using the fragment separator FRS at GSI. A significant increase of σ(-1n) for C-19 compared to its neighbors was observed. The same behavior was found for σ(-1p) for the neutron-deficient nucleus B-8 compared to the stable isotope B-10. These results support a one-neutron halo structure in C-19 and a one-proton halo in B-8.
