Resonant satellite transitions in argon [PDF]

open access: possiblePhysica Scripta, 1990
The production of specific Ar+ satellite states has been studied with synchrotron radiation at wavelengths between 300 and 350 A with an effective energy resolution of 20 meV. The specific states studied were the (3P)4p(2P3/2), (1D)4p(2F7/2), and (1D)4p(2P1/2) states.

Observations of transitions in satellite scintillation

Journal of Atmospheric and Terrestrial Physics, 1968
Abstract 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 ...

Energy systematics of the KαL satellite transitions

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1999
Abstract 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.

XPS satellites in transition metal oxides

Journal of Electron Spectroscopy and Related Phenomena, 1996
Abstract 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.

Intralesional Therapy for In-transit and Satellite Metastases in Melanoma

Surgical Oncology Clinics of North America, 2015
Intratumoral therapy with bacteria/bacterial products dates to at least the 1890s. Over the decades this has expanded beyond the use of microbes and microbial products to include chemicals, cancer chemotherapeutic agents, cytokines, recombinant organisms, and hybrid molecules.

Navy Navigation Satellite System (Transit)

IEEE Aerospace and Electronic Systems Magazine, 1987
The Navy Navigation Satellite System (TRANSIT) has provided 100% system reliability since being declared operational October 11, 1968. TRANSIT continues to carry out its function of precise, reliable, all weather navigation for the United States Navy and nearly 80,000 worldwide commercial users.

Satellite Transit at Seattle-Tacoma Airport [PDF]

open access: possibleTransportation Engineering Journal of ASCE, 1972
If 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 ...

Satellite Transition Spectroscopy of Quadrupolar Nuclei [PDF]

open access: possible, 1994
Magic-angle sample spinning (MAS) has had a major impact on several aspects of the development of NMR and its application to solid state physics and chemistry. MAS was first used to average out dipolar broadening in 23Na NMR of monocrystalline sodium chloride, as published in 1958 by Andrew, Bradbury and Eades [1].
