PEBSI - A Monte Carlo simulator for bremsstrahlung arising from electrons colliding with thin solid-state targets
Monte Carlo simulation polarized electrons bremsstrahlung polarization target-thickness effects hard x-ray
2012/5/31
We present a Monte Carlo code dedicated to the simulation of bremsstrahlung arising in collisions of polarized electrons with thin target foils. The program consists of an electron transport algorithm...
Propagation of gamma rays and production of free electrons in air
Propagation of gamma rays production of free electrons Plasma Physics
2012/4/20
A new concept of remote detection of concealed radioactive materials has been recently proposed \cite{Gr.Nusin.2010}-\cite{NusinSprangle}. It is based on the breakdown in air at the focal point of a h...

In a recent paper "Head-on collision of electron acoustic solitary waves in a plasma with nonextensive hot electrons" [Astrophys. Space Sci. 338, 271-278 (2012)] Eslami, Mottaghizadeh and Pakzad deal ...
On the zero-field orbital magnetic susceptibility of Bloch electrons in graphene-like solids: Some rigorous results
Diamagnetism zero-field susceptibility two-dimensional electrons gas graphene semiconductors
2012/4/17
Starting with a nearest-neighbors tight-binding model, we rigorously investigate the bulk zero-field orbital susceptibility of a non-interacting Bloch electrons gas in graphene-like solids at fixed te...
