Summary, in English

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