A theoreticalspectroscopy, abinitiobased study of the electronic ground state of 121SbH3
(Elsevier, 2010)For the stibine isotopologue (SbH3)Sb121, we report improved theoretical calculations of the vibrational energies below 8000 cm and simulations of the rovibrational spectrum in the 08000 cm(1) region. The calculations ... 
Anharmonicity effects in the bosonic U(2)SO(3) excitedstate quantum phase transition
(American Physical Society, 2010)We study the effect of the inclusion of the U(2) Lie algebra secondorder Casimir operator in a model Hamiltonian of the vibron model twodimensional limit. We extend previously published results, showing that the inclusion ... 
Rotational spectrum and tentative detection of DCOOCH3–Methyl formate in Orion
(American Astronomical Society, 2010)New centimeterwave (7–80 GHz) and submillimeterwave (580–661 GHz) spectra of a deuterated species of methyl formate (DCOOCH3) have been measured. Transitions with a maximum value of J = 64 and K = 36 have been assigned ... 
Theoretical investigation of the phase behaviour of model ternary mixtures containing nalkanes, perfluoronalkanes, and perfluoroalkylalkane diblock surfactants
(Taylor and Francis, 2010)We have used the heteroSAFTVR approach developed by McCabe and collaborators [Mol. Phys. 104, 571 (2006)] to investigate the phase equilibria of a number of binary and ternary mixtures of nalkanes, perfluoro nalkanes, ... 
Classical density functional theory for the prediction of the surface tension and interfacial properties of fluids mixtures of chain molecules based on the statistical associating fluid theory for potentials of variable range
(AIP Publishing, 2010)The statistical associating fluid theory for attractive potentials of variable range (SAFTVR) density functional theory (DFT) developed by [G. J. Gloor et al., J. Chem. Phys. 121, 12740 (2004)] is revisited and generalized ... 
Mean field study of structural changes in Pt isotopes with the Gogny interaction
(American Physical Society, 201002)The evolution of the nuclear shapes along the triaxial landscape is studied in the Pt isotopic chain using the selfconsistent HartreeFockBogoliubov approximation based on the Gogny interaction. In addition to the ... 
MATS and LaSpec: Highprecision experiments using ion traps and lasers at FAIR
(Springer, 201005)Nuclear ground state properties including mass, charge radii, spins and moments can be determined by applying atomic physics techniques such as Penningtrap based mass spectrometry and laser spectroscopy. The MATS and ... 
Relationship between X(5)models and the interacting boson model
(American Physical Society, 20100819)The connections between the X(5)models (the original X(5) using an infinite square well, X(5) 8, X(5) 6, X(5) 4, and X(5) 2), based on particular solutions of the geometrical Bohr Hamiltonian with harmonic potential ... 
Global assignment and extension of millimeter and submillimeterwave spectral database of 13C1methyl formate (H13COOCH3) in the ground and first excited states
(American Astronomical Society, 201009) 
Spectroscopy of protonunbound nuclei by tracking their decay products inflight: One and twoproton decays of (15)F, (16)Ne, and (19)Na
(American Physical Society, 20101129)A powerful method of investigating protonunbound nuclear states by tracking their decay prod ucts in °ight is discussed in details. To verify the method, four known levels in 15F, 16Ne, and 19Na were investigated by ... 
SDSS J162520.29+120308.7 – a new SU Ursae Majoris star in the period gap
(European Southern Observatory, 2011)We report results of an extensive worldwide observing campaign devoted to the recently discovered dwarf nova SDSS J162520.29+120308.7 (SDSS J1625). The data were obtained during the July 2010 eruption of the star and in ... 
Elastic scattering and αparticle production in 6He + 208Pb collisions at 22 MeV
(American Physical Society, 2011)Experimental results of the elastic scattering of 6He on 208Pb at ELAB = 22 MeV, measured at the CRC facility (LouvainlaNeuve, Belgium), are presented, including results on the 4He production channel. These data were taken ... 
On the massive gluon propagator, the PTBFM scheme and the lowmomentum behaviour of decoupling and scaling DSE solutions
(Springer Verlag, 2011)We study the lowmomentum behaviour of YangMills propagators obtained from Landaugauge DysonSchwinger equations (DSE) in the PTBFM scheme. We compare the ghost propagator numerical results with the analytical ones ... 
Reactions induced by 11Be beam at RexIsolde
(EDP Sciences, 2011)The collision induced by the three Beryllium isotopes, 9,10,11Be, on a 64Zn target were investigated at Ec.m. ≈ 1.4 the Coulomb barrier. The experiments with the radioactive 10,11Be beams were performed at the RexIsolde ... 
Dynamical probes of pairing correlations: twoparticle transfer and twoparticle breakup reactions
(IOP Publishing, 2011)We investigate the role played by pairing correlations in two typical classes of nuclear reactions specifically involving pairs of particles: twoparticle transfer reactions, where a pair of nucleons is exchanged between ... 
Equivalent rotations associated with the permutation inversion group revisited: symmetry projection of the rovibrational functions of methane
(Taylor & Francis, 2011)In this work the analysis of the equivalent rotations from the permutation inversion group formalism is revisited. We emphasize that explicit knowledge of changes in the Euler angles are not required in order to determine ... 
Phase diagram for a Cubic ConsistentQ Interacting Boson Model Hamiltonian : signs of triaxiality
