Department of Nuclear Reactions - Overview

Abstract

Full text: Our activity in 2008 has focused on well-established domains of research: nuclear and atomic physics, and applications. {center_dot} As far as nuclear physics is concerned; our interests are very broad, ranging from the structure of the nucleon to the structure of the nucleus including high-energy multifragmentation studies. Our colleagues led by Prof. Pawel Zupranski, members of the HERMES collaboration that comprises 32 institutions from eleven countries at the Deutsches Elektronen Synchrotron (DESY) in Hamburg, worked last year on the extraction of Spin Density Matrix Elements of vector mesons from scattering experiments on hydrogen targets. They also studied the distribution of quarks and gluons in nucleon. A team led by Prof. B. Zwieglinski was involved in the large-scale international collaboration PANDA (antiProton ANnihilation at DArmstadt). They studied the response of cooled PWO scintillators irradiated by gammas in the energy range of 4-20 MeV. The gammas were produced radiative proton capture on light by nuclei using a proton beam from the Van de Graaff accelerator of our Department. As a result, an important extrapolation of measurements performed by another group of physicists at much higher {gamma}-ray energies was obtained. Low energy nuclear physics experiments were continued at the Heavy Ion  More>>

The gammas were produced radiative proton capture on light by nuclei using a proton beam from the Van de Graaff accelerator of our Department. As a result, an important extrapolation of measurements performed by another group of physicists at much higher {gamma}-ray energies was obtained. Low energy nuclear physics experiments were continued at the Heavy Ion Laboratory of Warsaw University in collaboration with foreign institutions: the University of Jyvaeskylae, the Institute of Nuclear Research of the Ukrainian Academy of Science and the Institute de Recherches Subatomique in Strasbourg. At high energies, a study of the isospin - dependence of the caloric curve was performed by the ALADIN Collaboration in a series of experiments at GSI - Darmstadt using radioactive beams of Sn and La. It was found that the asymmetry due to isospin is very weak. {center_dot} Atomic physics studies were devoted to ionisation of heavy atoms by oxygen ions from the tandem accelerator of Erlangen-Nuernberg University. X-rays generated in the process of ionisation of gold atoms were detected and analyzed. {center_dot} Radiobiological studies were performed using carbon ions accelerated to energies in the range of 50-100 MeV at the Heavy Ion Laboratory of Warsaw University. In these experiments, the profile of the carbon beam was measured for the first time by means of nuclear track detector. This technique is much easier to use than scanning the beam profile with a (x,y) - movable silicon detector. {center_dot} Beams from our Van de Graaff accelerator LECH were used in particle - induced X-ray emission (PIXE) studies of polychromatic decorations in ancient Egyptian tombs. Important findings on the origin and dating of wall paintings at different archeological sites are reported. Finally, I would like to warmly welcome Mr Hamada Kotb who joined us last year. He will study ancient Egyptian ceramics by means of the PIXE technique. As always, apart from their purely scientific activities, a few of our colleagues have been involved in lectures and demonstrations prepared and presented for the general public. (author)}
