Badanie korelacji kątowych kwantów gamma za pomocą układu EAGLE
W pracy przedstawiono wyniki analizy danych z eksperymentów, w których metodą korelacji kątowych badano jądra 130Ba, 140Sm i 124Cs wyprodukowane z użyciem wiązek ciężkich jonów dostarczonych przez cyklotron U-200P należący ...
Hamiltonian formalisms and symmetries of the Pais–Uhlenbeck oscillator
(Elsevier B.V., 2014)
The study of the symmetry of Pais–Uhlenbeck oscillator initiated in Andrzejewski et al. (2014)  is continued with special emphasis put on the Hamiltonian formalism. The symmetry generators within the original Pais and ...
Generalized Niederer’s transformation for quantum Pais–Uhlenbeck oscillator
(Elsevier B.V., 2015)
We extend, to the quantum domain, the results obtained in [Nucl. Phys. B 885 (2014) 150] and [Phys. Lett. B 738 (2014) 405] concerning Niederer’s transformation for the Pais–Uhlenbeck oscillator. Namely, the quantum ...
Conformal Newton–Hooke algebras, Niederer's transformation and Pais–Uhlenbeck oscillator
(Elsevier B.V., 2014)
Dynamical systems invariant under the action of the l-conformal Newton–Hooke algebras are constructed by the method of nonlinear realizations. The relevant first order Lagrangians together with the corresponding Hamiltonians ...
Modification of thin films induced by slow heavy ions analysed with PIXE and SRIM
In the present work the particle induced X-rays (PIXE) emitted during interaction of inert and active slow heavy (HI) ions with specially prepared thin films were measured. Kinematics of the interaction was simulated ...
Hidden Lorentz symmetry of the Hořava–Lifshitz gravity
In this Letter it is shown that the Hořava–Lifshitz gravity theory admits Lorentz symmetry preserving preferred global time foliation of the spacetime.
β decay of 6He into the α+d continuum
(American Physical Society, 2015)
The rare β-decay channel of 6He into the α+d continuum was investigated at the REX-ISOLDE facility. Bunches of postaccelerated 6He ions were implanted into the optical time projection chamber (OTPC), where the decays with ...
Induced gravity and gauge interactions revisited
It has been shown that the primary, old-fashioned idea of Sakharov's induced gravity and gauge interactions, in the “one-loop dominance” version, works astonishingly well yielding phenomenologically reasonable results. As ...
