Estudio de la dinámica de partículas cargadas en una lámina de corriente de reconexión de una fulguración solar
(2014)
Se realiza una simulación de la aceleración mediante un campo eléctrico uniforme y constante (aceleración DC) que experimentarían electrones y protones al interior de una lámina de corriente durante una fulguración solar, ...
X-ray powder diffraction at the XRD1 beamline atLNLS
(Int Union Crystallography, 2016)
Various upgrades have been completed at the XRD1 beamline at the Brazilian synchrotron light source (LNLS). The upgrades are comprehensive, with changes to both hardware and software, now allowing users of the beamline to ...
Further investigating the determination of phosphorus in plants by INAA using bremsstrahlung measurement
(SPRINGERDORDRECHT, 2012)
Phosphorus is an essential element for plants and animals, playing a fundamental role in the production of biochemical energy. Despite its relevance, phosphorus is not commonly determined by instrumental neutron activation ...
Desenvolvimento de compósitos poliméricos com metais atenuadores e estudo da eficiência de atenuação da radiação para aplicação em procedimentos radiológicos
(Universidade Federal de Minas GeraisUFMG, 2016-08-11)
Poly(vinylidene-trifluorethylene) [P(VDF-TrFE)] polymer-based composites were developed by filling the polymer matrix with radiation attenuating metallic oxides in several concentrations, particularly the micro and nanosized ...
Double electron capture cross-sections by protons in collisions with He
(2009)
Double electron capture (DEC) by protons from He was studied in collisions at energies in the keV regime, theoretically and experimentally. Theoretical cross-sections were calculated using the electron nuclear dynamic ...

Electron detachment cross sections of CH4 - colliding with O2 and N2 below 10 keV energies
(2014)
Negative methane is an interesting molecular anion from a fundamental point of view and also because it can be a source of thermal electrons in low temperature hydrocarbon plasma. Measurements of collisional electron ...

A system to measure isomeric state half-lives in the 10 ns to 10 μs range
(2014)
The Isomeric State Measurement System (SISMEI) was developed to search for isomeric nuclear states produced by fusion-evaporation reactions. The SISMEI consists of 10 plastic phoswich telescopes, two lead shields, one ...
