Supercurrent Spectroscopy of Andreev States

open access: yesPhysical Review X, 2013
We measure the excitation spectrum of a superconducting atomic contact. In addition to the usual continuum above the superconducting gap, the single-particle excitation spectrum contains discrete, spin-degenerate Andreev levels inside the gap ...

Atomic absorption spectroscopy

open access: yesJournal of the American Oil Chemists' Society, 1968
AbstractAtomic absorption spectrophotometry has been used for the rapid determination of various metallic and nonmetallic elements in crude and refined vegetable oils and in animal fats, many present in levels of parts per million. Various types of crude and refined vegetable oils were analyzed for Ca, Cu, Fe, Mg, Mn, P and Zn.

DETERMINATION OF HEAVY METALS IN FOODSTUFFS BY ATOMIC ABSORPTION SPECTROPHOTOMETRY [PDF]

open access: yesFiabilitate şi Durabilitate, 2021
AAS uses the atomic ownership of absorbing electromagnetic radiation at certain wavelengths of infrared (IR), visible (VIS) or ultraviolet (UV) radiation, thus providing a detectable signal proportional to the concentration of atoms.

The nature of intrinsic recombination emission in SrSO4 irradiated with ultraviolet photons

open access: yesEurasian Journal of Physics and Functional Materials, 2021
The synthesized SrSO4 crystalline powders were irradiated at photon energies from 6 ÷ 12 eV, in the temperature range from 15 ÷ 300 K. The investigation was carried out by the methods of atomic absorption, luminescence and vacuum ultraviolet spectroscopy.
