We calculate K −-nucleus elastic differential, reaction and total cross sections for different nuclei (12 C, 40 Ca and 208 Pb) at several laboratory antikaon momenta, ranging from 127 MeV (momentum of an antikaon produced in the φ-meson decay) to 800 MeV. We use different antikaon-nucleus optical potentials, some of them fitted to kaonic atom data, and study the sensitivity of the results to th...

introduction: the septal region is part of the telencephalon and is a component of the limbic system. the lateral septal area (ls); largest nuclear mass in this region, plays a pivotal role in various physiological processes, such as aggression, emotion, thermoregulation, water and food intake and sexual behaviour. to support the functional analysis of this brain area in the rat, the sources of...

We investigate theoretically whether it is feasible to detect η-and ω-nucleus bound states. As well as the closed shell nuclei, 16 O, 40 Ca, 90 Zr and 208 Pb, we also investigate 6 He, 11 B and 26 Mg, which are the final nuclei in the proposed experiment involving the (d, 3 He) reaction at GSI. Potentials for the η and ω mesons in these nuclei are calculated in local density approximation, embe...

Autism may involve autoimmunity to brain. We studied regional distribution of antibodies to rat caudate nucleus, cerebral cortex, cerebellum, brain stem and hippocampus. The study included 30 normal and 68 autistic children. Antibodies were assayed by immunoblotting. Autistic children, but not normal children, had antibodies to caudate nucleus (49% positive sera), cerebral cortex (18% positive ...

Antiproton production from the secondary process pp~ pp is studied for nucleus-nucleus collisions at energies which are below the threshold for its production from the nucleon-nucleon reaction in the free space. In an expanding fireball model, we determine the p abundance from the fusion of pions and find that for collisions at 2. 1 GeV/nucleon the antiproton to negative pion ratio is = 5.5&10 ...

We study the disintegration of nuclei by strong electromagnetic fields induced by ultrarelativistic heavy ions. The proposed multi-step model includes 1) the absorption of a virtual photon by a nucleus, 2) intranuclear cascades of produced hadrons and 3) statistical decay of the excited residual nucleus. The combined model describes well existing data on projectile fragmentation at energy 200 G...
