[Radioactive cesium 137 and cesium 134 in follicle and seminal fluid].

Radioactive caesium nuclids were measured in follicular fluid and seminal plasma after the nuclear power station accident of Chernobyl. Immediately after the event (June - Aug. 86) both Cs 137 and Cs 134 were negative, with the exception of one sample. Increased levels of Cs 137 were found in the next three periods of measurement (Nov. 86 - Jan. 87), (June - Aug. 87), (March 88), with the highest results one year after the accident. Increased levels of Cs 134 were found only in the last two periods of measurement. In seminal plasma, both Cs 137 and Cs 134, were elevated in some samples. An influence on the results of IVF was not registered.

Proton production in relativistic heavy ion collisions; comparison with a thermodynamical model.

Experimental results concerning proton production in nuclear collisions, obtained at Saturne with the Diogene 4 pi facility, are compared with the predictions of a thermodynamical model, using collective velocity distributions combined with a statistical thermodynamics in local rest frames. Experimental differential cross sections for alpha + nucleus and Neon + nucleus central collisions at incident energies between 200 and 800 MeV per nucleon are well reproduced by the model, for an angular range 30-110 degrees in the laboratory system. Extracted values of the temperatures are compared with those given by other authors.

Nuclear collective flow and charged-pion emission in Ne-nucleus collisions at E/A = 800 MeV.

Triple-differential cross sections of charged pions were measured for collisions of Ne projectiles at E/A = 800 MeV with NaF, Nb, and Pb targets. The reaction plane was estimated event by event from the light-baryon momentum distribution. For heavy targets, preferential emission of charged pions away from the interaction zone towards the projectile side was observed in the transverse direction. Such a preferential emission, which is not predicted by cascade calculations, may be attributed to a stronger pion absorption by the heavier spectator remnant.
