Feeding Ecology and the Concentration of Organochlorines in Glaucous Gulls
We investigated the blood concentrations of organochlorines (OCs) and the diet of glaucous gulls Larus hyperboreus breeding in two neighbouring areas at Bear Island in the Barents Sea, north-eastern Atlantic. One...

Nucleon fragmentation into baryons in proton-nucleon interactions at 19 GeV/c compared with some quark-parton model predictions
We present some new data on baryon production in pn interactions at 19 G-eV/c obtained in a bubble chamber experiment. We determine the longitudinal-momentum spectradσ/dx of the baryon in the reactions pn → pF+X,...

Note on some charge exchange cross-sections of inelastic pn and pp reactions in terms of the quark interchange concept
In this note we discuss our observed charge exchange cross-sections of pN interactions at 19 GeV/c in terms of the quark-quark interchange concept. If one

Neutron fragmentation in the reaction pn→pX at 19 GeV/c
Data on the reaction pn→pX are extracted from a pd experiment in the CERN 2m DBC at 19 GeV/c. The cross-section for neutron fragmentation events with |t|<1 (GeV/c)2 is determined and compared with data at high en...

Neutron dissociation into pπ- at 19 GeV/cat 19 GeV/c
The reaction pn→ppπ at 19 GeV/c is studied. It is dominated by the process where the neutron dissociates into the pπ- system and exhibits the characteristic features of diffraction dissociation. The pπ- mass dist...

Charged-particle multiplicity distributions and rescattering effects in pd interactions at 19 GeV/c
Inelastic topological pd cross-sections at 19 GeV/c have been determined from an exposure of the CERN 2 m bubble chamber. The total cross-section for three or more prongs was measured to be (42.4±0.3) mb. The ...
