Conflict between the classical equivalence principle and quantum mechanics
(2009-05-11)
As far as external gravitational fields described by Newton's theory are concerned, theory shows that there is an unavoidable conflict between the universality of free fall (Galileo's equivalence principle) and quantum ...
GLUON SATURATION AND THE TOTAL PROTON-AIR CROSS SECTION
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2010)
In this work we propose a simple model for the total proton-air cross section, which is an improvement of the minijet model with the inclusion of a window in the p(T)-spectrum associated to the saturation physics. Our ...
Reaction functions for weakly bound systems
(ELSEVIER SCIENCE BV, 2009)
We propose a new technique to analyze total reaction cross sections. In this technique, which has been previously applied to fusion reactions, the experimental data are used to build a dimensionless reaction function, which ...
Experimental determination of multiple ionization cross sections in Si by electron impact
(American Physical Society, 2015-12)
The thin sample method is often used to experimentally determine ionization cross sections, especially when focusing on the low overvoltage region. The simplicity of the formalism involved in this method is very appealing, ...

Analysis of Fusion Cross Sections in the Be-9 Projectile Breakup on Different Target Nuclei
(Springer, 2020-10-24)
We present a theoretical study of total fusion (TF), complete fusion (CF), and incomplete fusion (ICF) cross sections in the breakup of Be-9 (described as n -Be-8) projectile on Sn-124, Sm-144 and Pb-208 target nuclei. We ...
L-shell X-ray production cross sections induced by protons and alpha-particles in the 0.7-2.0 MeV/amu range for Ru and Ag
(Elsevier Science, 2014-01)
The X-ray emissions induced by protons and alpha-particles of the elements Ag and Ru were measured onmono-elemental thin films. L-shell X-ray production cross sections were obtained for the three L-sub-shells, considering ...
Measurement of L X-ray production cross sections by impact of protons with energies between 2.5 MeV and 5.0 MeV in selected lanthanoids

A Simple and Efficient Device for Demonstrating Cross-sectional Anatomy of the Head
(WILEY-LISS, 2010)
Described in this article is a novel device that facilitates study of the cross-sectional anatomy of the human head. In designing our device, we aimed to protect sections of the head from the destructive action of handling ...
