 Lamb–Mössbauer factor

The Lamb–Mössbauer factor, often denoted as \( f \), is a key concept in the field of condensed matter physics and spectroscopy, particularly in relation to Mössbauer spectroscopy. It describes the fraction of the total intensity of a Mössbauer spectrum that is related to atoms that are well-ordered and not experiencing significant vibrational displacement or thermal motion.
