Mössbauer Spectrometer with Sample Exchanger

Sample volume investigation

General information

Usage

  • Transmission geometry, the gamma radiation is going through the sample, the detector on the other side is collecting absorption spectrum
  • Allows to study the sample under low temperatures

Sample types

  • Powder
  • Thin bulk samples (must be transparent for 14.4 keV gamma photon radiation)
