Mean free path of solar electrons and nucleons
نویسنده
چکیده
The quasilinear scattering mean free path of solar flare electrons and nucleons is calculated for interplanetary plasma wave turbulence consisting of a mixture of slab shear Alfvén waves and isotropic fast magnetosonic waves. It is shown that for well-sampled electron and nucleon mean free paths over a wide and overlapping energy range the underlying frequency power spectra of left-handed and right-handed slab Alfvén waves can be uniquely determined. Moreover, we demonstrate that the flatness and magnitude problems of quasilinear mean free paths of solar flare particles can be resolved if the interplanetary slab Alfvén magnetic power spectrum varies in wavenumber as ∝ |k|−s with s = 5/3 below |k| ≤ kc and s = 3 above |k| > kc where kc is the inverse of the ion skin length.

Mean free path and energy loss of electrons in the solar corona and the inner heliosphere
We have studied the mean free path of electrons in the solar atmosphere in dependence on their initial velocity and their starting height above the photosphere. The net pitch angle change results from the combined effects of Coulomb scattering and the decreasing field strength of the large-scale magnetic field. We show that above a certain velocity all electrons can travel a distance of at leas...

In this report, the distribution and deviation of electric field in the active medium of the TE CO2 laser has been investigated due to the injection of net electron charge beam as a plasma generator. Some parameters of system have been considered, such as density and mean-free-path of injected charge beam. The electric potential and electric field distribution have been simulated by solving the...
متن کاملObservation of Electrons from the Decay of Solar Flare Neutrons
We have found evidence for fluxes of energetic electrons in interplanetary space on board the ISEE-3 spacecraft which we interpret as the decay products of neutrons generated in a solar flare on 1980 June 21. The decay electrons arrived at the s/c shortly before the electrons from the flare and can be distinguished from the latter by their distinctive energy spectrum. The time profile of the de...
متن کاملA Variety of Giant Resonances in Metal Clusters
Metal cluster (MC) is a bound system consisting of atoms of some metal. The amount of atoms can vary from a few to many thousands. Some MC, mainly of alkali (Li, K, Na, ...) and noble (Ag, Au, ...) metals, demonstrate a striking similarity to atomic nuclei (see reviews). In these clusters the valence electrons are weakly coupled to the ions and, like nucleons in nuclei, are not strongly localiz...
متن کاملEvolution of Anomalous Cosmic-ray Oxygen and Helium Energy Spectra during the Solar Cycle 22 Recovery Phase in the Outer Heliosphere
We present annual 0.3–40 MeV nucleon 1 anomalous cosmic-ray (ACR) oxygen and helium energy spectra from the 1991–1999 cosmic-ray recovery phase of solar cycle 22. These observations were made with the Low Energy Charged Particle instruments aboard the Voyager 1 and Voyager 2 spacecraft while at helioradial positions ranging from 34 to 76 AU. The peak intensities of both species increased by 2 o...
