Combined theoretical and experimental study of the transmission of tilted ion beams through macroscopic conical glass capillaries
( IOP Publishing , 2015 , Conference Paper)The transmission as a function of the tilt angle of a 3 keV Ar+ ion beam through a conical macroscopic glass capillary is studied theoretically and experimentally. It was found that the charge patches which are responsible ... -

Ion impact induced ionization/fragmentation dynamics of rare gas Dimers
( IOP Publishing , 2013 , Conference Paper)We have measured the ionization and fragmentation of Helium, Neon and Argon Dimers induced by ion impact and observed two different pathways, the sequential ionization on each atom and the interatomic Cou-lombic decay. © ... -
Model for oscillations in the guidance of ions through insulating nanocapillaries
( IOP Publishing , 2011 , Conference Paper)The pre-equilibrium period of the ion guiding through insulating nanocapillaries is characterized by the production of temporary charge patches inside the capillaries. The dynamics of the charge patch creation is revealed ... -
Numerical bifurcation of predator-prey fractional differential equations with a constant rate harvesting
( IOP Publishing , 2008 , Article)In this article saddle and Hopf bifurcation points of predator-prey fractional differential equations system with a constant rate harvesting are investigated. The numerical results based on Grunwald-Letnikov discretization ... -
On the numerical simulation of population dynamics with density-dependent migrations and the Allee effects
( IOP Publishing , 2008 , Article)In this paper, the variational iteration method (VIM) and the Adomian decomposition method (ADM) are presented for the numerical simulation of the population dynamics model with density-dependent migrations and the Allee ...
