On the spectrum of fluctuations in the field emission
Proceedings International University Conference 'Electronics and Radiophysics of Ultra-High Frequencies' (Cat. No.99EX356), 2003The influence of probabilistic assumptions that determine the statistical model of multistable fluctuations in the field emission on the theoretical noise spectrum shape is studied.

Spectrum of the Galactic Radio Emission
Nature, 1965A NEW series of observations of the galactic radio emission has been conducted at the frequencies of 20, 30 and 85 Mc/s. These low-resolution observations made with scaled aerials were intended to investigate the spectral index of the galactic radio emission in the frequency region 10–100 Mc/s.

On the emission spectrum of molecular SbF
Journal of Physics B: Atomic and Molecular Physics, 1973The visible bands of SbF molecule have been photographed in a high frequency discharge at a dispersion of 7.5 AA/mm in the first order of a plane grating spectrograph. A new band system in the region lambda lambda 4730-5770 AA belonging to this molecule has been analysed and the vibrational constants are determined.

Although reports have shown shifts in carbon dot emission wavelengths resulting from varying the excitation wavelength, this excitation-dependent emission does not constitute true tuning, as the shifted peaks have much weaker intensity than their ...

Physical Review A, 1987
The two-photon emission spectrum of a strongly driven two-level atom is defined and calculated. Such a spectrum reveals details of non-Markovian dynamics which are not observable in the usual experiments. It is shown that a clear separation of Markovian and non-Markovian regimes is possible in the two-photon emission spectrum.

A spectrum analysis of acoustic emission
Non-Destructive Testing, 1975Abstract The authors describe a data acquisition system to determine the frequency spectrum between 500 KHz and 3 MHz of the initial acoustic emission. They measured the transfer function of the piezoelectric transducer and of the specimen for their results using a computer. They present an application of this device to the study of the emission of a

Measurement and model of the infrared two-photon emission spectrum of GaAs.
Physical Review Letters, 2009Two-photon emission from semiconductors was recently observed, but not fully interpreted. We develop a dressed-state model incorporating intraband scattering-related level broadening, yielding nondivergent emission rates.

THE EMISSION SPECTRUM OF THE CCI RADICAL
Canadian Journal of Physics, 1961A rotational analysis of the 2780 Å emission band obtained in a microwave discharge through CCl4 vapor and photographed on a 20-ft grating spectrograph shows that a 2Δi(b) → 2Πr(a) transition of the CCl radical is responsible, not 2Σ → 2Π(a) as reported by previous workers.

Spectrum in Atomic Emission Spectroscopy
2021An atomic emission spectrum of aluminum is discussed as a typical instance. The spectral lines are assigned to electronic transitions between the energy levels of the aluminum atom, based on the Russell-Saunders coupling (LS-coupling) and the selection rule described in Chap. 12.
