Energy Spectrum of Acoustic Emission Signals in Complex Media [PDF]

open access: yesЖурнал нано- та електронної фізики, 2017
A model of the energy spectrum of acoustic emission signals in complex structures with internal degrees of freedom is proposed. On the basis of the computational experiment of X-ray diffraction data, a quantum mechanical calculation of the applicability ...

Investigation of Er3+-Doped Phosphate Glass for L+ Band Optical Amplification

open access: yesIEEE Photonics Journal, 2021
In this work, Er3+-doped phosphate glass with good flatness of the emission spectrum of the L+ band was prepared by optimizing the content of BaO. The absorption and emission spectra were measured.

THE EMISSION SPECTRUM OF CURIUM [PDF]

open access: yesAtomic Data and Nuclear Data Tables, 1976
Abstract The curium emission spectrum was observed from 2400 to 11 200 A using electrodeless lamps as sources. Accurately measured wavelengths of 2034 of the strongest 244 Cm lines are reported. The wavelengths, wavenumbers, and relative intensities are given.

Spectrum of Singly Charged Uranium (U II) : Theoretical Interpretation of Energy Levels, Partition Function and Classified Ultraviolet Lines

open access: yesAtoms, 2017
In an attempt to improve U II analysis, the lowest configurations of both parities have been interpreted by means of the Racah-Slater parametric method, using Cowan codes.

Assessment of the degree of contamination of insulation by the radiation spectrum of surface partial discharges

open access: yesИзвестия высших учебных заведений: Проблемы энергетики
Unplanned overhead power line outages are typically associated with flashover of line insulation due to contamination and moisture. Powerful partial discharges on the insulation surface (SPD) can serve as a precursor to flashover. They can be detected by

Tailoring emission spectra by using microcavities

open access: yesResults in Physics, 2019
We present a theoretical model to describe emission spectrum of an emitter in a micro-cavity. Our model proposes that the spectrum in a metal micro-cavity depends on the product of the emission spectrum in free space and the local density of states (LDOS)
