Expectativas sociais e decisões jurídicas acerca do regime diferenciado de contratações públicas
(Universidade Federal de Santa MariaBrasilUFSMCentro de Ciências Sociais e Humanas, 2015-07-29)
This study aims to analyze social expectations (political, economic and legal)
that revolve around the Differentiated Regime of Public Contracts and legal decisions built in resolving litigations arising from the new ...
Light-particle single ionization of argon: Influence of the projectile charge sign
(American Physical Society, 2009-07)
The ionization of the 3p orbital of argon by incident electrons and positrons is studied by means of the post version of the continuum distorted wave–eikonal initial-state model. Results are presented at both 200 and 500 ...
Influence of the projectile charge sign in light particle single ionization of H2O
(Springer, 2019-05)
Positron- and electron-impact ionization of the 1b1 and 3a1 orbitals of H2 O is studied by meansof the CDW-EIS model at an impact energy of 81 eV. Fully differential cross sections are calculated andcontrasted after a ...
Evaluation of differential cross sections using classical two-active electron models for He
(Springer, 2019-01-10)
Differential cross sections for charge-exchange and single and double electronic emission in collisions of protons with He atoms at intermediate impact energies are theoretically evaluated by means of two classical trajectory ...
Double ionization of He by ion impact: Second-order contributions to the fully differential cross section
(American Physical Society, 2014-06)
In this work, we present a second-order Born series treatment for the double ionization of He by ion impact. In particular, we show that the well-known independent events and independent electron models naturally result ...
Differential electron emission in the ionization of Ne and Xe atoms under fast bare carbon ion impact
(IOP Publishing, 2015-06)
Measurement of the energy and angular distributions of the double differential cross section (DDCS) of electron emission from Ne and Xe atoms in collision with 5 MeV u-1 bare carbon ions is reported. This study aimed to ...
Fully differential cross sections in single ionization of helium by ion impact: Assessing the role of correlated wave functions
(Elsevier Science, 2008-02)
We study the effect of final state dynamic correlation in single ionization of atoms by ion impact analyzing fully differential cross sections (FDCS). We use a distorted wave model where the final state is represented by ...
Electron impact single ionization of the He-isoelectronic sequence
(Sociedade Brasileira de Física, 2007-09)
In this work, triply differential cross sections for single electron emission due to electron impact on the He-isoelectronic sequence are calculated by using a Born-C3 model. The influence of the nuclear charge on the ...
