A classical fluid description is used to investigate nonlinear interactions between an electron-type neutrino beam and a relativistic collisionless unmagnetized electron–positron plasma. It is shown that during the interaction a large amplitude wak

Measurements of energy distributions and reemission probabilities of epithermal positrons leaving Ag(100) are presented for incident positron energies E between 50 and 3000 eV. The width of the energy spectra increases as E decreases; about 18% of th

A method to detect 8B solar neutrinos is proposed using the charge current reaction νe19F with a hexafluorobenzene scintillation detector. The main advantage of the detector is the possibility of identifying neutrino events by a delayed coincidence

In order that confinement should survive, light quarks inside hadrons have a very high acceleration and will feel a thermal bath with an Unruh temperature near 137 MeV. We show that this temperature is consistent with the experimentally observed depa

The channeling yield of MeV antiprotons as a function of crystal depth is studied by computer simulation. It is found that a small fraction of channeled antiprotons penetrates anomalously into crystals.

For the calculation of the production of electron-positron pairs in ion-ion collisions at high energies we have formulated a continuum distorted wave model. Angular distributions of the emitted leptons are shown and discussed.

This paper presents kinetic equations for radiative energy losses and for the selfpolarization of a high energy beam taking into account multiple scattering in a bent plane potential. The numerical calculations have been carried out for TeV energy le

It is shown that the production of transversally polarized electrons and positrons by unpolarized γ-quanta with energies of tens and hundreds of GeV, is possible in thin crystal plates.
