Phonon Spectroscopy with Nuclear Inelastic Scattering of Synchrotron Radiation

Atomic dynamics of tin nanoparticles embedded into porous glass

“…The HRM instrumental function was measured in the same experiment by a second APD that was located in the photon beam transmitted through the sample and detected nuclear coherent for ward scattering. Additional information about the experimental setup, techniques, and data processing features can be found elsewhere [21][22][23].…”

“…In the case of tin, for which the Mössbauer isotope 119 Sn is known to exist, there is another, more attractive possibility of measuring the phonon DOS. This alternative is related to the use of a quite recently developed method of res onant nuclear inelastic scattering of X ray radiation [16][17][18][19][20][21][22][23]. Experimental implementation of this tech nique, which requires high intensity beams of X ray photons, became possible only since powerful sources of synchrotron radiation (SR) had been developed.…”

“…The small difference in the resonance width ( σ = 18.2(25) and 13.4(11) meV in Fig. 2 a and b, respectively) between these two resonance curves could be caused by the effects of the solid-state environment in the different targets: the resonance width is determined not only by the monochromator bandwidth but also by the target-dependent inelastic scattering processes corresponding to the phonon contributions in nuclear resonance scattering 26 , 27 .…”
