For a given number of electrons, total spin, and matching spin z-component, we construct a set that spans the many-electron spin subspace associated with these spin values. Each vector in the set is tensorially related to spin-pure vectors of six electrons or less. We show that in the limit of...

- Electron-electron bremsstrahlung for bound target electrons. Hauga, E. // European Physical Journal D -- Atoms, Molecules, Clusters & Opti;Feb2009, Vol. 49 Issue 2, p193
For the process of electron-electron (e-e) bremsstrahlung the momentum and energy distributions of the recoiling electrons are calculated in the laboratory frame. In order to get the differential cross section and the photon spectrum for target electrons which are bound to an atom, these...

Laser-induced acceleration of an electron injected initially at an angle to the direction of a circularly polarized laser pulse in the presence of an obliquely incident magnetic field has been investigated. For a suitable position of the peak of the laser pulse, the external magnetic field...

In this paper we examine the behavior of small cluster of atoms in a short (10-50 fs) very intense hard X-ray (10 keV) pulse. We use numerical modeling based on the non-relativistic classical equation of motion. Quantum processes are taken into account by the respective cross-sections. We show...

Impurity particle transport in tokamaks is studied using an electrostatic fluid model for main ion and impurity temperature gradient (ITG) mode and trapped electron (TE) mode turbulence in the collisionless limit and neoclassical theory. The impurity flux and impurity density peaking factor...

The effect of the weakly relativistic ponderomotive force in the interaction of an intense laser pulse with an underdense plasma is studied. This force modifies the electron density distribution. Furthermore, the existence of intense laser pulses in plasma causes the electron relativistic mass...
