... The first type of transition, shown in figure 2 (a), is known as resonant absorption. An electron transits from the stable low energy level, E1, to the higher energy level, E2, by absorbing light. Figure 2 (b) shows spontaneous emission.

Energy Spectra for Fractional Quantum Hall
... Fractional quantum Hall states (FQHS) with the filling factor ν = p/q of q < 21 are examined and their energies are calculated. The classical Coulomb energy is evaluated among many electrons; that energy is linearly dependent on 1/ν. The residual binding energies are also evaluated. The electron pai ...

Rutherford backscattering spectrometry
Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science. Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.
