Research capabilities

Mössbauer spectroscopy (57Fe-MS) is a nuclear research method based on the phenomenon of resonant absorption of low-energy gamma radiation. In geochemical research, it is used to analyze the phase composition and determine selected physicochemical parameters of geological materials. Iron atoms, which are probes in the studied material, provide information about their local chemical environment through hyperfine interactions.

Measurement capabilities

⁵⁷Fe-MS pozwala na: 1) jakościowe i ilościowe rozpoznanie minerałów zawierających żelazo, 2) wyznaczenie stosunku Fe³⁺/Fe²⁺, 3) identyfikację lokalnej krystalicznej geometrii koordynacyjnej.

Pomiary wykonywane są na próbkach proszkowych o masie od 10 mg (miligram) do 100 mg. Metoda jest nie-destrukcyjna i po pomiarze próbka może być wykorzystana do dalszych badań innymi metodami.
