Observations have shown that, prior to substorm explosions, thin current sheets are formed in the plasma sheet of the Earth's magnetotail. This provokes the question, to what extent current-sheet thinning and substorm onsets are physically, maybe

Current sheet acceleration as well as reconnection are two major ion acceleration processes in space plasma and, therefore, their general characteristics have been well investigated in the past. Now, howeve, with the new opportunities of modern satel

Based on analytical calculations we have currently argued that spontaneous reconnection through thin collisionless current sheets is an essentially three-dimensional (3 D) process (Buchner, 1996 a, b). Since 3 D kinetic PIC codes have become availabl

New Perspectives on the Earth'S Magnetotail
The GEOTAIL project has provided rich information about the ionic composition of the magnetotail in general and about the mass-dependent spectra of energetic ions in particular. These measurements have encouraged further efforts toward a better under

The energy distribution of protons sputtered from a metallic glass sample Zr50Ni25Cu25 with 90% hydrogen embedded in the lattice was investigated. The energy distribution was measured for various energies of the primary Ar+ ions. It turns out that th

The dependence of sputtering yields are calculated on the incidence angle for a semi-infinite target. Basic ideas for a more correct description of the experimental situation in sputtering at oblique incidence were developed by Sigmund in 1981. The t

When solid metal surfaces are bombarded with energetic ions slow particles are emitted in both neutral and ionized states. The collision cascades produced by the penetrating ions can lead to spatial disorder at the metal surface. The influence of thi

The absorbing boundary conditions for the one- and two-dimensional Schrodinger equation on a finite interval are considered by using a rational-diction approximation for the dispersion relation. The approximation gives good results over a wide range
