The analysing power for the p(pol)p --> pp eta reaction at Q=10 MeV
R. Czyzykiewicz, P. Moskal, H. -H. Adam +29
The analyzing power A_y for the p(pol)p --> pp eta reaction has been determined at the beam momentum p_{beam}=2010 MeV/c, corresponding to the excess energy Q=10 MeV. In the paper…
Eta and eta' mesons production at COSY-11
P. Moskal, H. -H. Adam, A. Budzanowski +24
The low emittance and small momentum spread of the proton and deuteron beams of the Cooler Synchrotron COSY combined with the high mass resolution of the COSY-11 detection system p…
Tight-binding model of spin-polarized tunnelling in (Ga,Mn)As-based structures
P. Sankowski, P. Kacman, J. Majewski +1
The Landauer-Buettiker formalism combined with the tight-binding transfer matrix method is used to describe the results of recent experiments: the high tunneling magnetoresistance…
Study of the 3He-eta system in d-p collisions at COSY-11
J. Smyrski, H. -H. Adam, A. Budzanowski +27
We present preliminary results from dp --> 3He X (X=pi0,eta) measurements near the eta production threshold. The data were taken during a slow ramping of the COSY internal deuteron…
STRIP-PET: a novel detector concept for the TOF-PET scanner
P. Moskal, T. Bednarski, P. BiaÅas +22
We briefly present a design of a new PET scanner based on strips of polymer scintillators arranged in a barrel constituting a large acceptance detector. The solution proposed is ba…
TOF-PET detector concept based on organic scintillators
P. Moskal, T. Bednarski, P. BiaÅas +22
In this contribution we present a new concept of the large acceptance detector systems based on organic scintillators which may allow for simultaneous diagnostic of large fraction…
Hadronic interaction of the eta meson with two nucleons
P. Moskal, H. -H. Adam, A. Budzanowski +21
The COSY-11 collaboration has conducted experiments aiming at the determination of the excitation function and phase-space population of the p p --> p p eta reaction close to the k…
A method to disentangle single- and multi-meson production in missing mass spectra from quasi-free pn --> pn X reactions
P. Moskal, H. -H. Adam, A. Budzanowski +25
The separation of contributions from multi- and single-meson production in the missing mass spectrum of the quasi-free pn --> pnX reaction constitutes a~challenging task when the r…
Study of the production mechanism of the eta meson by means of analysing power measurements
R. Czyzykiewicz, P. Moskal, H. -H. Adam +26
Information about the production mechanism of the eta meson in proton-proton collisions can be inferred by confronting the experimental studies on the analysing power for the p(pol…
Near threshold eta meson production in dp collisions
C. Piskor-Ignatowicz, J. Smyrski, P. Moskal +23
Preliminary results of recent measurements of the near threshold eta meson production in the dp-->dp eta reaction are presented. The experiment was performed at the COSY-Juelich ac…
Evaluation of commercial nickel-phosphorus coating for ultracold neutron guides using a pinhole bottling method
R. W. Pattie, E. Adamek, T. Brenner +24
We report on the evaluation of commercial electroless nickel phosphorus (NiP) coatings for ultracold neutron (UCN) transport and storage. The material potential of 50~m thick N…
Correlation Femtoscopy for Studying Eta Meson Production Mechanism
P. Klaja, P. Moskal, H. -H. Adam +27
The high statistics data from the pp -> ppeta reaction measurement, delivered by the COSY-11 collaboration, are now being evaluated using the correlation femtoscopy technique. This…
Near threshold production of the eta meson via the quasi-free pn --> pn eta reaction
P. Moskal, R. Czyzykiewicz, H. -H. Adam +29
Total cross sections for the quasi-free pn --> pn eta reaction in the range from the kinematical threshold up to 20 MeV excess energy have been determined. At threshold they exceed…
