Production of neutrons in reaction of relativistic protons on thick or how to burn the nuclear waste by accelerator
Krása, V. ; Wagner, Vladimír ; Belina, L. ; Henzlová, D. ; Henzl, V. ; Kugler, Andrej ; Adam, Jindřich ; Čaloun, Pavel ; Krivopustov, M. I. ; Tumendelger, Th.
We look for the way how to burn the nuclear waste by the transmutation of radioactive nuclei by the fast neutrons produced by proton beam.

Heavy-ion collisions: The study of elliptic flow of neutral mesons in Au+Au reaction at 800 A MeV
Pleskač, Radek ; Kugler, Andrej ; Tlustý, Pavel ; Wagner, Vladimír ; Hlaváč, S.
The combination of the photon spectrometer TAPS - an electromagnetic calorimeter with good energy, time and spatial resolution - and the charged particle-detecting KAOS Forward Wall (FW) offers the possibility to study azimuthal distribution of neutral mesons relative to the reaction plane. The experimental data from the Au+Au reaction at 800 MeV were analyzed. The reaction plane was determined on an event by event by event basis and angular distribution of ă.sup.o./sup. and .eta. mesons was reconstructed. The observed elliptic flow signal is negative for .eta. mesons, indicating a preferred emission perpendicular to the reaction plane. The elliptic flow for ă.sup.o./sup. mesons is significantly observed in peripheral Au+Au collisions only.

Electron-positron pair production in nuclear matter - first data from HADES
Tlustý, Pavel ; Kugler, Andrej ; Pleskač, Radek ; Wagner, Vladimír ; Suk, M. ; Hlaváč, S. ; Žovinec, D.
Study of hadron properties inside nuclear matter at normal and high temperatures and baryon densities represents one of important topics of the present nuclear research. Several models predict change of effective masses and widths of hadrons due to the chiral symmetry restoration at extreme conditions of the nuclear matter. Existing experimental data do not allow unambiguous conclusions with respect to medium modifications due to the limited invariant mass resolution and separation. To improve and extend the existing experimental evidence the new High Acceptance DiElectron Spectrometer HADES was build at GSI, Darmstadt.
