XPS satellites in transition metal oxides
Journal of Electron Spectroscopy and Related Phenomena, 1996Abstract The core levels of different transition metal oxides have been measured by X-ray photoelectron spectroscopy. All core level lines are accompanied by a complex satellite structure which is similar for all core lines. These satellites originate from shake processes.

Observations of transitions in satellite scintillation
Journal of Atmospheric and Terrestrial Physics, 1968Abstract A sub-auroral region of ionospheric irregularities with a well-defined equatorward boundary produces sharp transitions in the scintillation observed on VHF signals from the beacon satellite BE-B recorded at three New Zealand stations. Triangulation shows that the irregularities are located at heights between 240 km and 600 km, with about ...

Extended Applications Of The Transit Navigation Satellite Transit System
Offshore Technology Conference, 1971ABSTRACT The Transit Navigation Satellite System has been used principally for obtaining discrete position fixes while underway. Also, in most installations the satellite equipment has operated independently of other shipboard navigation sensors. This paper describes two new applications of the Transit System.

K X-ray satellite transitions in cobalt
Zeitschrift für Physik, 1974Bombardment of cobalt with 42 MeV oxygen ions is seen to produce multiple inner shell electron excitation.Kα andKβ X-rays are measured and compared to Hartree-Fock-Slater calculated energies. This study of cobalt is the highestZ element where the satellite X-ray spectrum has been studied with good resolution.

Dielectronic recombination satellite transitions in dense plasmas
Journal of Quantitative Spectroscopy and Radiative Transfer, 2000Abstract Radiative and dielectronic recombination of multiply charged many-electron ions in high-temperature plasmas are usually treated as independent, non-interfering processes. A projection-operator and resolvent-operator approach has been developed to provide a fundamental, unified quantum-mechanical description of the combined electron–ion photo-

Transit, the Navy Navigation Satellite System
Navigation, 1971So much has happened in this world since October 4, 1957, it is difficult to realize that fewer than 14 years have passed since the launch of Sputnik I, the first artificial earth satellite. Technology has leapt forward from those first "beeps" in space to produce worldwide communication and weather monitoring systems, spies-in-the sky, astronomical ...

Energy systematics of the KαL satellite transitions
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1999Abstract The presence of X-ray satellites is common in X-ray spectra. The last compilation of satellite lines, frequently cited in the open literature, is the X-ray energy collection of Cauchois and Senemaud, Wavelengths of X-ray Emission Lines and Absorption Edges, Pergamon, Oxford, 1978 [1] , which is restricted to electron and photon excitations.

17O satellite transition spectroscopy of amorphous SiO2
Journal of Non-Crystalline Solids, 1993Abstract The increase of spectral resolution of the 3 2 ↔ 1 2 (− 1 2 ↔ − 3 2 satellite transition spinning sidebands of 17 O NMR has been demonstrated for amorphous SiO 2 . Even for large quadrupole coupling constants ( C Q ≈ 5 MHz), the spinning sidebands can be observed.

Satellite Transit at Seattle-Tacoma Airport
Transportation Engineering Journal of ASCE, 1972If transportation within airports is to keep pace with the revolution in travel habits that has occurred over the past few years, systems of automated horizontal movement are clearly required to complement the escalator and elevator. Such a system at Seattle-Tacoma International Airport will soon afford the public (and airline and airport personnel) a ...

SSETO—Small Satellite for Exoplanetary Transit Observation
Acta Astronautica, 2014Abstract SSETO is the result of a phase-A study in context of the small satellite program of the University of Stuttgart that demonstrates the capability of a university institute to build a small satellite with a budget of 5 million Euro. The satellite will be capable of observing exoplanets in a Neptune–Earth scale and obtaining data of ...
