Counterion correlations and attraction between like-charged macromolecules
(2001) [Artigo de periódico]A simple model is presented for the appearance of attraction between two like-charged polyions inside a polyelectrolyte solution. The polyions are modeled as rigid cylinders in a continuum dielectric solvent. The strong ... -
Interplay between the Coulomb explosion and vicinage effects studied using H/sub 2//sup +/ molecules under channeling conditions
(2006) [Artigo de periódico]The aim of this work is to investigate how the mean energy loss and straggling due to H2 + molecules interacting with silicon are affected by the Coulomb explosion and vicinage effects. To that end, a SIMOX-type sample ... -
Measurements of L-shell x-ray production cross sections of W, Pt, and Au by 10-30-keV electrons
(2002) [Artigo de periódico]We present results from measurements of Lα x-ray production cross sections of the elements W, Pt, and Au by impact of electrons with energies in the range 10–30 keV. The cross sections were obtained by measuring Lα x-ray ... -
Monte Carlo simulation of x-ray spectra generated by kilo-electron-volt electrons
(2003) [Artigo de periódico]We present a general algorithm for the simulation of x-ray spectra emitted from targets of arbitrary composition bombarded with kilovolt electron beams. Electron and photon transport is simulated by means of the general-purpose ... -
Observation of collective inner-shell effects for protons backscattered from the Al(110) surface
(2005) [Artigo de periódico]The surface peak of 98-keV protons backscattered from a clean Al (110) surface has been studied in detail for three different scattering geometries. The corresponding energy-loss distributions are asymmetric due to the ...
