We present experimental and theoretical results of vicinage effects due to the interaction of H+ 2 and H+ 3 molecules with thin gold foils. High-energy-resolution backscattering experiments were carried out at energies ranging from 80 up to 200 keV p

As frutas são ricas em minerais, sendo estes essenciais para uma grande variedade de processos metabólicos e fisiológicos no corpo humano. A utilização de frutas congeladas tem se ampliado nos últimos anos, não só na preparação de sucos, ma

We report the direct etching of Al2O3 and SiO2 using 900-keV Au+ ions. 2000-mesh Cu grids were employed as masks using two different configurations: 1 the Cu mesh was placed on top of each insulator separately and independent irradiations were perfor

Si x-ray and backscattering yields have been measured as a function of the C⁺ and C₂⁺ entrance angle along the Si ‹100› channel in an energy interval between 900 and 2200 keV/atom. A significant enhancement of the x-ray production has been

Si-K x-ray and backscattering yields have been measured as a function of the projectile entrance angle for atomic and molecular (H2 + and H3 +) hydrogen ions channeling at kinetic energies of 150 keV per proton along the Si k100l crystal direction. A

The energy loss of helium ions in zinc has been measured in the energy range from 37.5 to 1750 keV/amu using the transmission technique and the Rutherford backscattering method. In addition, calculations using the extended Friedel sum rule, the unita

Angular distributions of tritons emitted in the reaction ⁷Li(y,t)α have been measured for two photon energy intervals (6.4–6.7 and 8.5–9.0 MeV), and θt between 30° and 150°. Monochromatic photons from neutron capture reactions of the IPEN/C

Dice throwing is used to illustrate relevant concepts of the statistical theory of uncertainties, in particular the meaning of a limiting distribution, the standard deviation, and the standard deviation of the mean. It is an important part in a seque
