Neutron capture cross sections for the Re/Os clock
(AIP Publishing, 2005)
The radioactive decay of 187Re → 187Os (t 1/2 = 43 Gyr) is suited for dating the onset of heavy-element nucleosynthesis. The radiogenic contribution to the 187Os abundance is the difference between the natural abundance ...

95 MeV neutron scattering on hydrogen, deuterium, carbon, and oxygen
(American Physical Society, 2006-12-05)
Three neutron-deuteron scattering experiments at 95 MeV have been performed recently at The Svedberg Laboratory in Uppsala. Subsets of the results of these experiments have been reported in two short articles, showing clear ...

A dynamic density functional theory for particles in a flowing solvent
(AIP Publishing, 2007-12)
We present a dynamic density functional theory dDFT which takes into account the advection of the particles by a flowing solvent. For potential flows, we can use the same closure as in the absence of solvent flow. The ...

Theory of capillary-induced interactions beyond the superposition approximation
(AIP Publishing, 2007-11)
Within a general theoretical framework, we study the effective, deformation-induced interaction between two colloidal particles trapped at a fluid interface in the regime of small deformations. In many studies, this ...

Bilayered smectic phase polymorphism in the dipolar Gay-Berne liquid crystal model
(AIP Publishing, 2009)
We present computer simulations of the Gay–Berne model with a strong terminal dipole. We report the existence of different stable antiferroelectric interdigitated bilayered phases in this model with diverse in-plane ...

α-particle production in the scattering of 6He by Pb-208 at energies around the Coulomb barrier
(Elsevier, 2007)
New experimental data from the scattering of 6He + Pb-208 at energies around and below the Coulomb barrier are presented. The yield of breakup products coming from projectile fragmentation is dominated by a strong group ...

Continuous unitary transformations in two-level boson systems
(American Physical Society, 2005-12-01)
Two-level boson systems displaying a quantum phase transition from a spherical (symmetric) to a deformed (broken) phase are studied. A formalism to diagonalize Hamiltonians with O(2L+1) symmetry for large number ...

Induced ferromagnetism in Mn3N2 phase embedded in Mn/Si3N4 multilayers
(AIP Publishing, 2009)
Room temperature ferromagnetism has been obtained for different sets of Mn/Si3N4 multilayers prepared by sputtering. In order to find the most suitable conditions to stabilize the ferromagnetic ordering in this system, ...

O18+Pd110: Measurements and realistic coupled-channel analysis in a transitional region
(American Physical Society, 2006)
The inelastic, two-neutron and α transfer and quasielastic cross sections for the 18O+110Pd system have been measured in the near barrier region (40 MeV Elab 58 MeV). The experiments were performed in the S˜ao Paulo ...
