Cluster scattering in the non-local model

Frontiers in Physics, 2023
Scattering of weakly bound nuclei with a pronounced cluster structure is strongly affected by their breakup. Usually, this mechanism is accounted for in a three-body model with pairwise potentials.

Elastic and inelastic scattering of 18O ions on 12C nuclei [PDF]

Ядерна фізика та енергетика, 2009
Angular distributions of the 12C + 18O elastic and inelastic scattering were measured at the energy Elab(18O) = 105 MeV (Ec.m. = 42 MeV). These data and data known from the literature at the energies Ec.m. = 12.9 - 56 МеV were analysed within the optical

Time-independent approximations for time-dependent optical potentials [PDF]

, 2019
We explore the possibility of modifying the Lewis-Riesenfeld method ofin-variants developed originally to find exact solutions for time-dependent quantum me-chanical systems for the situation in which an exact invariant can beconstructed, butthe ...

Study of $^{6}$He+$^{12}$C Elastic Scattering Using a Microscopic Optical Potential

, 2010
The $^6$He+$^{12}$C elastic scattering data at beam energies of 3, 38.3 and 41.6 MeV/nucleon are studied utilizing the microscopic optical potentials obtained by a double-folding procedure and also by using those inherent in the high-energy approximation.

Quantum Hall-like effect for cold atoms in non-Abelian gauge potentials

, 2007
We study the transport of cold fermionic atoms trapped in optical lattices in the presence of artificial Abelian or non-Abelian gauge potentials. Such external potentials can be created in optical lattices in which atom tunneling is laser assisted and ...

Digital reconstruction of optically-induced potentials

Optics Express, 2009
The holographic reconstruction of optically-induced objects typically assumes that the object is axially thin. Here, we demonstrate a simple approach that works for axially thick objects which evolve dynamically. Results are verified by reconstructing linear scattering experiments in a self-defocusing photorefractive crystal.

The 6Li(18O, 17O)7Li reaction mechanisms and 7Li + 17O potential [PDF]

Ядерна фізика та енергетика, 2012
Angular distributions of the 6Li(18O, 17O)7Li reaction were measured at Elab(18O) = 114 MeV for ground and excited states of exit nuclei. The data were analyzed within the coupled-reaction-channels method (CRC).

The Abnormal Threshold Anomaly in the 6Li + 208Pb System [PDF]

EPJ Web of Conferences
Numerous studies have demonstrated that the phenomenological optical potential of tightly bound nuclear systems presents a threshold anomaly phenomenon in the near-Coulomb barrier energy region, where the relationship between the real and imaginary ...

Coherent transport of neutral atoms in spin-dependent optical lattice potentials

, 2003
We demonstrate the controlled coherent transport and splitting of atomic wave packets in spin-dependent optical lattice potentials. Such experiments open intriguing possibilities for quantum state engineering of many body states.
