Neutron capture cross section of unstable 63Ni: implications for stellar nucleosynthesis
(American Physical Society, 2013-01-08)
The 63Ni(n,γ) cross section has been measured for the first time at the neutron time-of-flight facility n_TOF at CERN from thermal neutron energies up to 200 keV. In total, capture kernels of 12 (new) resonances were ...

The 2011 October Draconids outburst-I. Orbital elements, meteoroid fluxes and 21P/Giacobini-Zinner delivered mass to Earth
(Oxford University Press, 2013)
On 2011 October 8, the Earth crossed the dust trails left by comet 21P/Giacobini-Zinner during its 19th and 20th century perihelion approaches with the comet being close to perihelion. The geometric circumstances of that ...

Quasi-elastic processes of the 48Ca + 120Sn system and the 48Ca nuclear matter density
(American Physical Society, 2013)
We present the results of a high-precision quasi-elastic excitation function measurement for the 48Ca + 120Sn system at θLAB = 160 at near-barrier energies in steps of 1.0 MeV. The corresponding quasi-elastic barrier ...

Combination of fast-ion diagnostics in velocity-space tomographies
(IOP Publishing, 2013-06)
Fast-ion Dα (FIDA) and collective Thomson scattering (CTS) diagnostics provide indirect measurements of fastion velocity distribution functions in magnetically confined plasmas. Here we present the first prescription ...

Statistics of work and fluctuation theorems for microcanonical initial states
(IOP Publishing Ltd., 2013)
Work performed on a system in a microcanonical state by changes in a control parameter is characterized in terms of its statistics. The transition probabilities between eigenstates of the system Hamiltonians at the beginning ...

Linear hydrodynamics for driven granular gases
(American Physical Society, 2013)
We study the dynamics of a granular gas heated by a stochastic thermostat. From a Boltzmann description, we derive the hydrodynamic equations for small perturbations around the stationary state that is reached in the long ...

Novel dual single sided silicon strip detector chip for radiotherapy verification
(Scuola Internazionale Superiore di Studi Avanzati (S I S S A), 2013)
A novel dual single sided silicon strip detector (SSSSD) chip was designed to meet clinical requirements in radiotherapy verification. An available design from Micron Semiconductor Ltd. (BB7, 500 µ m thick) was the base of ...

Uniform self-diffusion in a granular gas
(American Institute of Physics, 2013)
A granular gas composed of inelastic hard spheres or disks in the homogeneous cooling state is considered. Some of the particles are labeled and their number density exhibits a time-independent linear profile along a given ...

11Li Breakup on 208Pb at Energies Around the Coulomb Barrier
(American Physical Society, 2013-04-05)
The inclusive breakup for the 11Li+208Pb reaction at energies around the Coulomb barrier has been measured for the first time. A sizable yield of 9Li following the 11Li dissociation has been observed, even at energies well ...
