Evidence for Time-Varying Nuclear Decay Rates: Experimental Results and Their Implications for New Physics
Time-Varying Nuclear Decay Rates New Physics
2011/7/20
Unexplained annual variations in nuclear decay rates have been reported in recent years by a number of groups. We show that data from these experiments exhibit not only variations in time related to E...
Transport-theoretical Description of Nuclear Reactions
Transport-theoretical Description Nuclear Reactions
2011/7/21
In this review we first outline the basics of transport theory and its recent generalization to off-shell transport. We then present in some detail the main ingredients of any transport method using i...
Neutrino Quasielastic Scattering on Nuclear Targets: Parametrizing Transverse Enhancement (Meson Exchange Currents)
Neutrino Quasielastic Nuclear Targets Parametrizing Transverse Enhancement
2011/7/21
We present a parametrization of the observed enhancement in the transverse electron quasielastic (QE) response function for nucleons bound in carbon as a function of the square of the four momentum tr...

Nuclear reaction rates determine the abundances of isotopes in stellar burning processes.A multitude of reactions determine the reaction flow pattern which is described in terms of reaction network si...
Nuclear absorption effects on Lambda-bar/p-bar ratio in heavy ion collisions
Nuclear absorption effects Lambda-bar/p-bar ratio heavy ion collisions
2011/1/6
An enhanced ¯ /¯p ratio in heavy-ion relative to p + p collisions has been proposed as one of the signatures for the Quark-Gluon Plasma (QGP) formation. A significantly large (¯ +0 +...

Effective Field Theory and High-Precision Calculations of Nuclear Electroweak Processes
Effective Field Theory High-Precision Calculations Nuclear Electroweak Processes
2010/12/29
High-precision calculations of electroweak processes in light nuclei are of great importance for multiple reasons. Gerry Brown together with Dan-Olof Riska published in 1972 a famous calculation on ra...
Curvature effect on nuclear pasta: Is it helpful for gyroid appearance?
Curvature effect nuclear pasta gyroid appearance
2011/1/6
In supernova cores and neutron star crusts, nuclei are thought to deform to rod-like and slablike shapes, which are often called “nuclear pasta.” We study the equilibrium properties of the nuclear pas...
We present measurements of both $p_t$-integral and $p_t$-differential azimuth quadrupole components of two-particle correlations on azimuth ($\phi$) and pseudorapidity ($\eta$) for unidentified hadron...
Coherent state transfer between an electron- and nuclear spin in 15N@C60
Coherent state transfer electron- and nuclear spin
2010/11/25
Electron spin qubits in molecular systems o er high reproducibility and the ability to self assemble into larger architectures. However, interactions between neighbouring qubits are `always-on' and al...
Nuclear spins, magnetic moments and quadrupole moments of Cu isotopes from N = 28 to N = 46: probes for core polarization effects
Nuclear spins magnetic moments quadrupole moments Cu isotopes probes core polarization effects
2010/12/31
Measurements of the ground-state nuclear spins, magnetic and quadrupole moments of the copper isotopes from 61Cu up to 75Cu are reported. The experiments were performed at the ISOLDE facility, using t...

Nuclear coherent population transfer x-ray laser pulses
2010/12/27
Coherent population transfer in a nuclear three-level system via stimulated Raman adiabatic passage is studied. To compensate for the lack of $\gamma$-ray laser sources, we envisage accelerated nucle...
