electron spectrum

The figure on the right shows the electron spectrum of Hg, measured by means of a magnetic spectrometer.

Electron spectra were obtained during two rocket flights into pulsating aurora from Southend, Saskatchewan.

Comparisons with recent calculations of the coincident electron spectra and parameters characterising the resonance states are presented for different kinematic conditions.

A very soft electron spectrum was observed, which was comparable with a Maxwellian distribution of E0 ≤ 10 eV.

At this point, the bound state electron spectrum overlaps with the positron continuum and positrons may be produced (for example, in heavy ion collisions).

Altitude profiles of the volume emission rate resulting from each process are computed for Maxwellian electron spectra with characteristic energies between 0.1 and 2.0 keV.

Electron spectra with Maxwellian energy distributions were observed in both flights with an increase in characteristic energy during each pulsation.

New calculations of the 6300-Å:4728-Å column emission-rate ratio are presented for a range of characteristic energies in an assumed Maxwellian electron spectrum.

An Auger electron spectrum contains peaks corresponding to the intensity of Auger electrons as a function of their kinetic energy.

A recent re-analysis of reference electron spectra data from the Institut Laue-Langevin has also hinted at a fourth, sterile neutrino.

Neutrino mass Several experiments have performed to measurements of the neutrino mass by examining the endpoint of the electron spectrum in beta decay.

A positive detection of this effect would allow to measure the low energy electron spectrum, to constrain the magnetic field energy density and to test the equipartition hypothesis.

His research specialties are in condensed matter theory, particularly in the field of excited state electronic structure and the theory of X ray and electron spectra.

Auger electron energies can be calculated based on measured values of the various and compared to peaks in the secondary electron spectrum in order to identify chemical species.

The electron spectrum producing this soft X-ray source agrees well with in situ satellite and rocket-borne measurements of electron spectra during active auroras.

High-resolution electron spectra of these complexes are obtained using pulsed-field ionization zero electron kinetic energy (ZEKE) photoelectron spectroscopy.

The only true continuum is produced by the recombination of electrons with ions, which results in a continuum according to the energy characteristics of the free electron spectrum and the recombination cross section.

Auger electron spectra showed the presence of Fe, Ti and O. Surface structure models for the (0001) plane of ilmenite, consistent with the LEED data, will be presented.

To make progress in the theoretical treatment of solvated electron spectra attention should be focussed on the separate values of g and l and their temperature dependences; the width at half height W1/2 thereby loses theoretical significance.

During the 1910s and 1920s, through the study of electron spectra from the nuclear beta decay, it became apparent that, in addition to an electron, another particle with very small mass and with no electric charge is emitted in the beta-decay but not observed.

CALET is an astrophysics mission that searches for signatures of dark matter and provides the highest energy direct measurements of the cosmic ray electron spectrum in order to observe discrete sources of high-energy particle acceleration in our local region of the galaxy.

The set of data presented is sufficiently complete to allow, when used together with other types of experiments such as the height distribution of the optical intensity and the high-energy electron spectra, the achievement of the objective of the ARIES multi-instrument campaign, i.e., refinement of the auroral model.
