Physicists conduct most precise measurement yet of interaction between atoms and carbon surfaces
Physicists most precise measurement atoms and carbon surfaces
2015/6/18
Physicists at the University of Washington have conducted the most precise and controlled measurements yet of the interaction between the atoms and molecules that comprise air and the type of carbon s...
Measurement of airborne 131I, 134Cs, and 137Cs nuclides due to the Fukushima reactors accident in air particulate in Milan (Italy)
Airborne radioactivity, Fukushima accident, 131I, 137Cs and 134Cs
2011/9/5
After the earthquake and the tsunami occurred in Japan on 11th March 2011, four of the Fukushima reactors had released in air a large amount of radioactive isotopes that had been diffused all over the...
Measurement of damping and temperature: Precision bounds in Gaussian dissipative channels
Measurement damping temperature Precision bounds Gaussian dissipative channels
2010/10/29
We present a comprehensive analysis of the performance of different classes of Gaussian states in the estimation of Gaussian phase-insensitive dissipative channels. In particular, we investigate the ...
Measurement of the gamma gamma* --> eta_c transition form factor
gamma gamma momentum transfer
2010/3/15
We study the reaction e+e- --> e+e- eta_c, eta_c --> K_S K+- pi-+ and obtain eta_c mass and width values 2982.2+-0.4+-1.6 MeV/c^2 and 31.7+-1.2+-0.8 MeV, respectively. We find Gamma(eta_c --> gamma ga...
The $B_c^\pm$ mass and lifetime measurements using the decay $B_c^\pm \to J/\psi \pi^\pm$ at the LHCb experiment were studied. About 310 signal events are expected for a data set which corresponds to ...
In order to better understand the breakup contribution to fusion, we perfomed light particle coincidence measurements for the systems 6;7Li+12C,59Co at energies near and above the barrier. A three bod...
Measurement of Inelastic-Scattering Cross Sections in the 16O+28Si System to Discriminate Regular and Chaotic Regimes
Inelastic-Scattering Cross Sections the 16O+28Si System Regular and Chaotic Regimes
2010/10/25
A new experiment to measure differential cross sections as a function of the bombarding energy and scattering angle for the 16O +28 Si system in order to discriminate regular and chaotic regimes, was ...
