Applications of neutron activation spectroscopy
Since the discovery in 1932, neutrons became a basis of many methods used not
only in research, but also in industry and engineering. Among others, the
exceptional role in the modern nuclear engineering is played by the neutron
activation spectroscopy, based on the interaction of neutron flux with atomic
nuclei. In this article we shortly describe application of this method in
medicine and detection of hazardous substances.Comment: Presented at Symposium on applied nuclear physics and innovative

Study of the final state interaction in proton-proton and electron-positron collisions
The strength of the kaon--antikaon interaction is a crucial quantity for many
physics topics. It is for example, an important parameter in the discussion on
the nature of the scalar resonances and , in
particular for their interpretation as molecules. So far, one of the
few possibilities to study this interaction is the kaon pair production in
multi particle exit channels like . In this article we present
the latest results of the interaction preformed based on near
threshold data gathered at the Cooler Synchrotron COSY. We discuss also shortly
perspectives for a new measurement of the kaon--antikaon scattering length in
the collisions.Comment: Proceedings of the Excited QCD 2013 Workshop, Bjelasnica Mountain,

Improved tagging procedure and its impact on physics at KLOE-2
The KLOE experiment at the DANE -factory performed precise
studies of charged and neutral kaon physics, low energy QCD, as well as tests
of CP and CPT invariance. For the new run the KLOE has been upgraded by adding
new tagger systems for the physics, the inner tracking chamber
and two calorimeters in the final focusing region. We are also improving on
kaon identification techniques, in particular algorithms for the meson
tagging. In this article we discuss the impact of the improved tagging
procedure on studies of the decays.Comment: 5 pages, 2 figure
The KLOE-2 experiment at DAFNE
The KLOE-2 experiment at the INFN Laboratori Nazionali di Frascati (LNF) is
currently taking data at the upgraded DAFNE collider. Present Run
II follows a~development phase to assess the feasibility of a long term
acquisition program, Run I, which successfully ended in July 2015 with 1
fb integrated luminosity collected in less than eight months. KLOE-2
represents the continuation of the KLOE experiment with a new physics program.
The KLOE detector has undergone several upgrades including state-of-the-art
cylindrical GEM Inner Tracker, electron-positron taggers for the
-physics studies and new calorimeters around the interaction
point. In this article we briefly present the overview of the KLOE-2 experiment
including the present status and achievements together with the physics plans.Comment: 6 pages, 3 gigures, Submitted to EPJ Web of Conference
Phenomenological studies of the low energy dynamics in the system
In this article we review studies of the near threshold
reaction done with the COSY-11 and ANKE detectors. We discuss phenomenological
studies of the dynamics, in particular the recent investigations on
the final state interaction are presented.Comment: Proceedings of the EFB22 conference (4 pages, 1 figure
Combined analysis of the interaction using near threshold data
The final state interaction was investigated based on both the
invariant mass distributions measured at excess energies of Q = 10
and 28 MeV and the near threshold excitation function for the reaction. The final state enhancement factor was
parametrized using the effective range expansion. The effective range of the
interaction was estimated to be: and , and the
determined real and imaginary parts of the scattering length amount
to: and .Comment: 5 pages, 3 figures, article accepted for publication in Phys. Rev.
Close to threshold eta' meson production in proton-proton collisions at COSY-11
Intensive quest for the eta and eta' bound states is currently ongoing at
both theoretical and experimental levels e.g. at COSY, ELSA, GSI, JINR, JPARC,
LPI, and MAMI. These studies were already supported by data provided by the
COSY-11 collaboration including determination of the total width of the eta'
meson. In addition, the first rough estimation of the eta'-N interaction from
the excitation function of the cross section for the pp-->pp eta' reaction was
also performed. Recent precise measurement in this field from the COSY-11
experiment allows to summarize results on the eta' meson production cross
section in proton-proton collisions at COSY-11.Comment: 4 pages, 1 figure, presented at 13th International Workshop on Meson
