A calculation of lowlying collective states in oddeven nuclei [Article]
(Elsevier, 1984)We present results of a calculation of properties of lowlying collective quadrupole states in oddeven nuclei within the framework of the protonneutron interacting bosonfermion model.

A dispersive optical model potential for nucleon induced reactions on 238 U and 232 Th nuclei with full coupling [Article]
(EDP sciences, 2013)A dispersive coupledchannel optical model potential (DCCOMP) that couples the groundstate rotational and lowlying vibrational bands of 238U and 232Th nuclei is studied. The derived DCCOMP couples almost all excited ...

A dynamic density functional theory for particles in a flowing solvent [Article]
(AIP Publishing, 200712)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 ...

A fast edge charge exchange recombination spectroscopy system at the ASDEX Upgrade tokamak [Article]
(AIP Publishing, 2017)In this work, a new type of high throughput CzernyTurner spectrometer has been developed which allows us to acquire multiple channels simultaneously with a repetition time on the order of 10 μ s at different wavelengths. ...

A fast readout electronic system for accurate spatial detection in ion beam tracking for the next generation of particle accelerators [Article]
(Institute of Electrical and Electronics Engineers Inc, 2015)This paper presents the design, implementation, and measurements of a complete electronic frontend intended for highresolution spatial detection of ion beams at counting rates higher than 106 particles per second (p/s). ...

A forward model for the helium plume effect and the interpretation of helium charge exchange measurements at ASDEX Upgrade [Article]
(IOP Science, 20180323)The analysis of the charge exchange measurements of helium is hindered by an additional emission contributing to the spectra, the helium ‘plume’ emission (Fonck et al 1984 Phys. Rev. A 29 3288), which complicates the ...

A general algebraic model for molecular vibrational spectroscopy [Article]
(Elsevier, 1996)We introduce the anharmonic oscillator symmetry model to describe vibrational excitations in molecular systems exhibiting a high degree of symmetry. A systematic procedure is proposed to establish the relation between the ...

A general numerical solution of dispersion relations for the nuclear optical model [Article]
(IOP Publishing, 20010716)A general numerical solution of the dispersion integral relation between the real and the imaginary parts of the nuclear optical potential is presented. Fast convergence is achieved by means of the GaussLegendre integration ...

A HartreeBose meanfield approximation for IBM3 [Article]
(Springer Nature, 1998)A HartreeBose meanfield approximation for the IBM3 is presented. A HartreeBose transformation from the spherical to the deformed bosons with chargedependent parameters is proposed which allows bosonic pair correlations ...

A highly sensitive method for the reassessment and quantification of 239Pu in urine samples based on a 1 MV accelerator mass spectrometry system [Article]
(2010)A new and highly sensitive method for the determination of 239Pu in human urine has been developed permitting the reassessment of planchets initially prepared for alpha spectrometry (AS) analysis in the context of internal ...

A Lane consistent optical model potential for nucleon scattering on actinide nuclei with extended coupling [Article]
(EDP sciences, 2016)An extension for oddA actinides of a previously derived dispersive coupledchannel optical model potential (OMP) for 238U and 232Th nuclei is presented. It is used to fit simultaneously all the available experimental ...

A large lunar impact blast on September 11th 2013 [Article]
(Oxford University Press, 2014)On 2013 September 11 at 20h07m28 .s 68 ± 0 .s 01 UTC, two telescopes operated in the framework of our lunar impact flashes monitoring project recorded an extraordinary flash produced by the impact on the Moon of a large ...

A local anharmonic treatment of vibrations of methane [Article]
(1997) 
A new beam emission polarimetry diagnostic for measuring the magnetic field line angle at the plasma edge of ASDEX Upgrade [Article]
(AIP Publishing, 2016)A new edge beam emission polarimetry diagnostic dedicated to the measurement of the magnetic field line angle has been installed on the ASDEX Upgrade tokamak. The new diagnostic relies on the motional Stark e ff ect ...

A new CVD Diamond MosaicDetector for (n, α ) CrossSection Measurements at the n TOF Experiment at CERN [Article]
(Elsevier, 2013)At the n\_TOF experiment at CERN a dedicated singlecrystal chemical vapor deposition (sCVD) Diamond MosaicDetector has been developed for (n,alpha) crosssection measurements. The detector, characterized by an excellent ...

A novel orientationdependent potential model for prolate mesogens [Article]
(American Institute of Physics, 2005)An intermolecular potential is introduced for the study of molecular mesogenic fluids. The model combines distinct features of the wellknown GayBerne and Kihara potentials by incorporating dispersive interactions ...

A phenomenological imaginary part of the optical potential for heavy ions [Article]
(Elsevier, 1983)The depth of the imaginary part of the optical potential is derived from the assumption that, at a given energy and for each partial wave L, it is proportional to the compound nucleus density level up to a given excitation ...
