The three first-order energies probed by this technique are the shift in atomic electrostatic energy due to nuclear excitation, the level split to interactions between the nuclear quadrupole and crystal field, and the level split due to magnetized nuclear excited states: those are respectively the isomer shift, electric quadrupole split, and nuclear Zeeman effect. This probing method usually uses narrow-lined cobalt-57 as its source though, at high temperatures, calculations of the source energy for this technique must be shifted by a second-order Doppler shift. The fraction of source emissions suitable for this probe is given by the Debye-Waller factor since this technique combines the Doppler effect with its namesake recoil-free emission of photons, an effect that is itself named for the German who discovered it in iridium.
