Comment Head-on collision of electron acoustic solitary waves nonextensive hot electrons Space Physics
2012/4/20
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 ...
Nuclear collision in strong magnetic field
Nuclear collision strong magnetic field isospin physics
2011/7/20
We studied nucleus-nucleus collision in strong magnetic field based on a transport model. It is found that neutrons and protons can be separated from a nucleus by strong magnetic field and neutron-ric...
Effect of isospin dependent cross-section on elliptic flow in heavy-ion collision at intermediate energies
heavy-ion collision cross-section isospin dependent
2011/7/20
We study the elliptical flow of fragment in heavy-ion collisions for different systems at incident energies between 40 and 1200 MeV/nucleon using an isospin-dependent quantum molecular dynamics model....
Electron loss of fast heavy projectiles in collision with neutral targets
Electron loss neutral targets
2011/9/5
The multiple electron loss of heavy projectiles in fast ion-atom collisions has been studied in the framework of the sudden perturbation approximation. Especially, a model is developed to calculate th...

Coupled-channels density-matrix approach to low-energy nuclear collision dynamics: A technique for quantifying quantum decoherence effects on reaction observables
Coupled-channels density-matrix low-energy nuclear collision dynamics reaction observables
2010/11/11
The coupled-channels density-matrix technique for nuclear reaction dynamics, which is based on the Liouville-von Neumann equation with Lindblad dissipative terms, is developed with the inclusion of fu...
KEKB Beam Collision Stability at the Picosecond Timing and Micron Position Resolution as observed with the Belle Detector
beam axis SuperKEKB collider beam train
2010/3/15
Using the Belle detector we study the characteristics of beam collisions at the KEKB 3.5 GeV $e^+$ on 8 GeV $e^-$ asymmetric energy collider. We investigate the collision timing {\tip} and its $z$-coo...
Elementary Statistical Models for Vector Collision-Sequence Interference Effects with Poisson-Distributed Collision Times
Elementary Statistical Models Collision Times Vector Collision-Sequence
2009/9/4
In a recent paper (Lewis, 2008) a class of models suitable for application to collision-sequence interference was introduced. In these models velocities are assumed to be completely randomized in each...
