Determination of Recoil-Free Fractions From 151Eu Mossbauer Spectra of EuBO3
… levels, may be imparted to the nucleus as it recoils, much as a gun acquires energy in recoiling after firing a bullet. This energy is termed the recoil energy associated with the transition. Consequently the energy of the emitted photon differs from the transition energy.

Production of Ultra-Thick Sodium Nitroprusside Absorbers for the Determination of Mössbauer Transmission Integral Parameters.
… al., introduced a novel method for determining recoil-free fractions, namely, the spectra of a series of thicknesses of absorbers are fitted simultaneously under a least squares minimization criterion to the transmission integral. This technique, when applied to 151Eu (source) and EU2O3 …
