Investigation of the role of neutron transfer in the fusion of 32,34S with 197Au,208Pb using quasi-elastic scattering [PDF]

, 2005
Excitation functions for quasi-elastic scattering have been measured at backward angles for the systems 32,34S+197Au and 32,34S+208Pb for energies spanning the Coulomb barrier.

Fusion and quasi-fission dynamics in nearly-symmetric reactions

, 2015
Some nearly-symmetric fusion reactions are systematically investigated with the improved quantum molecular dynamics (ImQMD) model. By introducing two-body inelastic scattering in the Fermi constraint procedure, the stability of an individual nucleus and ...

Strong coupling effects on near-barrier 15C + 208Pb elastic scattering

Physics Letters B
The presence of a neutron halo in 15C has been demonstrated in several reaction experiments at intermediate energies. In the present study, the dynamical effects of this structure are observed for the first time at Coulomb barrier energies in the 15C ...

A Lane consistent optical model potential for nucleon scattering on actinide nuclei with extended coupling

EPJ Web of Conferences, 2016
An extension for odd-A actinides of a previously derived dispersive coupledchannel optical model potential (OMP) for 238U and 232Th nuclei is presented. It is used to fit simultaneously all the available experimental databases including neutron strength ...

Fluctuating magnetic moments in liquid metals

, 2005
We re-analyze literature data on neutron scattering by liquid metals to show that non-magnetic liquid metals possess a magnetic moment that fluctuates on a picosecond time scale.

Rhodopsin Photoactivation Dynamics Revealed by Quasi-Elastic Neutron Scattering [PDF]

Biophysical Journal, 2015
Rhodopsin is a G-protein-coupled receptor (GPCR) responsible for vision under dim light conditions. During rhodopsin photoactivation, the chromophore retinal undergoes cis-trans isomerization, and subsequently dissociates from the protein yielding the opsin apoprotein [1].

Neutron scattering from a coordination polymer quantum paramagnet [PDF]

, 2006
Inelastic neutron scattering measurements are reported for a powder sample of the spin-1/2 quantum paramagnet $\rm Cu(Quinoxaline)Br_2$. Magnetic neutron scattering is identified above an energy gap of 1.9 meV.

New evaluation of thermal neutron scattering libraries for light and heavy water

EPJ Web of Conferences, 2017
In order to improve the design and safety of thermal nuclear reactors and for verification of criticality safety conditions on systems with significant amount of fissile materials and water, it is necessary to perform high-precision neutron transport ...

Quasi-Elastic Neutrino Reactions on Carbon and Lead Nuclei

, 2017
We examine neutral-current quasi-elastic neutrino-nucleus reactions on $^{12}$C and $^{208}$Pb targets. We use the relativistic mean field theory approach to describe the nuclear dynamics.
