Critical-point symmetries in Boson-Fermion systems: The case of shape transitions in odd nuclei in a multiorbit model
(American Physical Review, 2007-02-05)
We investigate phase transitions in boson-fermion systems. We propose an analytically solvable model [E(5/12)] to describe odd nuclei at the critical point in the transition from the spherical to γ-unstable behavior. In ...

Few-body multiple scattering calculations for 6 He on protons
(American Physical Society, 2007)
The elastic scattering of the halo nucleus 6 He from a proton target at 717 MeV/nucleon is investigated within three different multiple-scattering formulations of the total transition amplitude. The factorized impulse a ...

Shape-phase transitions and two-particle transfer intensities
(The American Physical Society, 2007)
In the light of renewed interest in experiments on two-particle transfer reactions, we study the evolution of the transfer spectroscopic intensities as a possible signature of shape-phase transitions. The study is carried ...

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 ...

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 ...

The 139 La(n ,γ) cross section: Key for the onset of the s -process
(The American Physical Society, 2007)
The nuclear resonance parameters and the capture cross section of the neutron magic isotope La139 have been measured relative to Au197 in the energy range of 0.6 eV to 9 keV at the neutron time-of-flight (n_TOF) facility ...

The nature of the gould belt from a fractal analysis of its stellar population
(IOP Publishing Ltd., 2007-09-20)
he Gould Belt (GB) is a system of gas and young, bright stars distributed along a plane that is inclined with respect to the main plane of the Milky Way. Observational evidence suggests that the GB is our closest star ...

Observation of two-proton radioactivity of Mg19 by tracking the decay products
(American Physical Society, 2007-10-29)
We have observed the two-proton radioactivity of the previously unknown 19Mg ground state by tracking the decay products in-flight. For the first time, the trajectories of the 2p-decay products, 17Ne+p+p, have been measured ...
