Desenvolvimento de uma cápsula selada de 22Na para produção de feixe de pósitrons
(Universidade Federal de Juiz de Fora (UFJF)BrasilICE – Instituto de Ciências ExatasPrograma de Pós-graduação em FísicaUFJF, 2017)
Aplicações do modelo molecular no estudo de complexos de positron: taxa de aniquilação, relaxação molecular e espalhamento
(Universidade Federal de Minas GeraisUFMG, 2009-10-02)
In this work we present applications of the molecular model to the study of positron interaction with atoms and molecules. In this model, the positron is treated as a light nucleus and its motion can be completely separated, ...
Caos em um sistema pósitron-molécula
(Universidade Federal de Minas GeraisUFMG, 2018-08-10)
The classical trajectories for a positron interacting collinearly with a vibrating molecule, are calculated in a search for a chaotic scattering behavior. The positron-molecule interaction has been modelled via coupled ...
Near threshold vibrational excitation of molecules by positron impact: A projection operator approach
(ELSEVIER SCIENCE BV, 2008)
We report vibrational excitation (v(i) = 0 -> v(f) = 1) cross-sections for positron scattering by H(2) and model calculations for the (v(i) = 0 -> v(f) = 1) excitation of the C-C symmetric stretch mode of C(2)H(2). The ...
The Schwinger multichannel method (SMC) calculations for Z(eff) were off by a factor of Z

Low energy scattering of positrons by H2O

Multicenter continuum-distorted-wave eikonal-initial-state description of the electron-impact ionization of aligned H2 molecules
(American Physical Society, 2020-10-12)
In this work, the multicenter continuum-distorted-wave (CDW) eikonal-initial-state (EIS) model is introduced. In contrast to previously reported CDW EIS analyses for electron-molecule collisions, in which the ionized ...
