Quantum Correlations in NMR systems
In conventional NMR experiments, the Zeeman energy gaps of the nuclear spin
ensembles are much lower than their thermal energies, and accordingly exhibit
tiny polarizations. Generally such low-purity quantum states are devoid of
quantum entanglement. However, there exist certain nonclassical correlations
which can be observed even in such systems. In this chapter, we discuss three
such quantum correlations, namely, quantum contextuality, Leggett-Garg temporal
correlations, and quantum discord. In each case, we provide a brief theoretical
background and then describe some results from NMR experiments.Comment: 21 pages, 7 figure
Measurement of differential cross section for proton-induced deuteron breakup at 108 MeV
The experiment was performed at CCB IFJ PAN in Kraków with the use of the BINA detector. The experimental program and data analysis of proton-induced deuteron breakup reaction at 108 MeV are presented
Measurement of differential cross sections for deuteron-proton breakup reaction at 160 MeV
Differential cross sections for deuteron breakup reaction
were measured for a large set of 243 geometrical configurations at the beam
energy of 80 MeV/nucleon. The cross section data are normalized by the
luminosity factor obtained on the basis of simultaneous measurement of elastic
scattering channel and the existing cross section data for this process. The
results are compared to the theoretical calculations modeling nuclear
interaction with and without taking into account the three-nucleon force (3NF)
and Coulomb interaction. In the validated region of the phase space both the
Coulomb force and 3NF play an important role in a good description of the data.
There are also regions, where the improvements of description due to including
3NF are not sufficient
Measurement of differential cross sections for the deuteron-proton breakup reaction at 160 MeV

The cross-section data are normalized by the luminosity factor obtained on the basis of a simultaneous measurement of the elastic-scattering channel and the existing cross-section data for this process.
