197 - Au(n, gamma) cross section in the resonance region

Massimi, C.; Rosetti, M.; Ventura, A. (2010-04-27)

The (n, gamma) cross section of 197 - Au has been measured at n_TOF in the resolved resonance region, up to 5 keV, with the aim of improving the accuracy in an energy range where it is not yet considered standard. The ...
197_Au (n,γ) cross section in the unresolved resonance region

Rosetti, M.; Ventura, A. (2011-03-17)

The cross section of the reaction 197_Au(n,γ) was measured with the time-of-flight technique at the n_TOF (neutron time-of-flight) facility in the unresolved resonance region between 5 and 400 keV using a pair of C6D6 ...
1D Josephson quantum interference grids: Diffraction patterns and dynamics

Corato, V. (Institute of Physics Publishing, 2016)

We investigate the magnetic response of transmission lines with embedded Josephson junctions and thus generating a 1D underdamped array. The measured multi-junction interference patterns are compared with the theoretical ...
210Pb and 210Po concentrations in Italian cigarettes and effective dose evaluation

Bartolomei, P. (2014)

It has been known for a long time that cigarette tobacco contains naturally occurring radioactive nuclides such as 210Pb and 210Po. In this study, the concentrations of 210Pb and 210Po in the 10 most widely sold cigarette ...
210Pb mass accumulation rates in the depositional area of the Magra River (Mediterranean Sea, Italy)

Delbono, I.; Barsanti, M.; Schirone, A.; Conte, F.; Delfanti, R. (Elsevier Ltd, 2016)

Nine sediment cores were collected between 2009 and 2012 in the inner continental shelf (Mediterranean Sea, Italy) mainly influenced by the Magra River, at water depths ranging from 11 to 64 m. Mass Accumulation Rates ...
25 Years of Self-Organized Criticality: Solar and Astrophysics

Milovanov, A.V. (Springer Netherlands, 2016)

Shortly after the seminal paper “Self-Organized Criticality: An explanation of 1/fnoise” by Bak et al. (1987), the idea has been applied to solar physics, in “Avalanches and the Distribution of Solar Flares” by Lu and ...
25 Years of Self-organized Criticality: Space and Laboratory Plasmas

Milovanov, A.V. (Springer Netherlands, 2015)

Studies of complexity in extended dissipative dynamical systems, in nature and in laboratory, require multiple approaches and the framework of self-organized criticality (SOC) has been used extensively in the studies of ...
3D remote colorimetry and watershed segmentation techniques for fresco and artwork decay monitoring and preservation
