The time evolution of the coherent decay of a collective nuclear excitation (nuclear exciton), induced by 14.4 keV synchrotron radiation, was studied in a system of two stainless steel foils, where one was vibrated by ultrasound (US). The US vibratio

We have observed scattering of synchrotron radiation by the 9.4-keV nuclear resonance of gaseous {sup 83}Kr. In a gas, there is no recoilless absorption (no Moessbauer effect). A cell of krypton gas (natural abundance, 12% {sup 83}Kr) was placed afte

Specular scattering of x rays by electrons in a material becomes large at grazing angles below the critical angle for external reflection. In contrast, we observe specular scattering by resonant nuclei to peak at the critical angle and decrease at sm

We have measured the efficiencies and time responses of several large-area (200 and 80 mm2) beveled-edge avalanche photodiodes to X-rays of energy 6–20 keV in a photon counting mode. The diodes were used with avalanche gains of 102 to 103. Detector

It is shown that the hyperfine field in a crystal can be characterized in a short measurement using resonant nuclear diffraction at a high‐brightness synchrotron x‐ray beamline. In addition to the strength of the field, this technique is sensitiv

Nuclear resonant scattering of synchrotron radiation was investigated simultaneously in the spatially incoherent $(4\ensuremath{\pi})$ and in the spatially coherent (forward) scattering channels. A theory is presented which describes the main contrib

We report the first observation of excitation of the 6.2 keV nuclear level of ${}^{181}\mathrm{Ta}$ by synchrotron radiation. The absolute energy of the level was determined to be $6214\ifmmode\pm\else\textpm\fi{}2$ eV. The time distribution of nucle

The Mossbauer effect can sometimes be used to determine the relative abundances of different phases for a given element in a sample. For example, a radioactive element bound in a silicon-based glas...
