Gamma rays are electromagnetic radiation at the short-wavelength, or high-frequency, end of the electromagnetic (EM) spectrum, which ranges from gamma rays (short) to radio (long). The study and analysis of gamma-ray spectra for scientific and technical use is called gamma spectroscopy, and gamma-ray spectrometers are the instruments which observe and collect such data. Because the energy of each photon of EM radiation is proportional to its frequency, gamma rays have sufficient energy that they are typically observed by counting individual photons. 2, record 1, English, - gamma%2Dray%20spectrometer

La spectrométrie Mössbauer est une méthode permettant de déterminer le degré d’oxydation et l'environnement d’éléments chimiques [Un] échantillon est bombardé par un rayonnement gamma(photons) dont on fait varier l'énergie autour d’une énergie de transition nucléaire […] Un détecteur se trouve derrière l'échantillon. Lorsque l'énergie du rayonnement incident correspond à l'énergie de transition électronique, le rayonnement est absorbé, et donc l'intensité collectée est faible. Il s’agit donc d’une spectrométrie d’absorption. Le spectre Mössbauer est constitué d’un ensemble de multiplets dont la forme et la position(déplacement chimique) est à la fois caractéristique du nombre d’oxydation, mais aussi de la nature et de la géométrie des plus proches voisins de l'élément chimique étudié. 2, record 2, French, - spectre%20M%C3%B6ssbauer
