Half-life of 31Si
Giancarlo D'Agostino, Marco Di Luzio, Giovanni Mana +1
Half-life values are widely used in nuclear chemistry to model the exponential decay of the quantified radionuclides. The analysis of existing data reveals a general lack of inform…
30Si Mole Fraction of a Silicon Material Highly Enriched in 28Si Determined by Instrumental Neutron Activation Analysis
Giancarlo D'Agostino, Marco Di Luzio, Giovanni Mana +3
The latest determination of the Avogadro constant, carried out by counting the atoms in a pure silicon crystal highly enriched in 28Si, reached the target 2x10-8 relative uncertain…
Improved measurement results for the Avogadro constant using a 28Si-enriched crystal
Y Azuma, P Barat, G Bartl +26
New results are reported from an ongoing international research effort to accurately determine the Avogadro constant by counting the atoms in an isotopically enriched silicon cryst…
Instrumental neutron activation analysis of an enriched 28Si single-crystal
G. DAgostino, L. Bergamaschi, L. Giordani +2
The determination of the Avogadro constant plays a key role in the redefinition of the kilogram in terms of a fundamental constant. The present experiment makes use of a silicon si…
The detection of signals buried in noise
Luigi Bergamaschi, Giancarlo D'Agostino, Laura Giordani +2
This paper examines signal detection in the presence of noise, with a particular emphasis to the nuclear activation analysis. The problem is to decide what between the signal-plus-…
Perturbations of the local gravity field due to mass distribution on precise measuring instruments: a numerical method applied to a cold atom gravimeter
G. D'Agostino, S. Merlet, A. Landragin +1
We present a numerical method, based on a FEM simulation, for the determination of the gravitational field generated by massive objects, whatever geometry and space mass density th…
Comparison of 3 absolute gravimeters based on different methods for the e-MASS project
A. Louchet-Chauvet, S. Merlet, Q. Bodart +5
We report on the comparison between three absolute gravimeters that took place in April 2010 at Laboratoire National de Métrologie et d'Essais. The three instruments (FG5#209 from…
