“…In the special case ω = θ, one detects the specular radiation. A well-known property of the 'ω-scan' intensity function is its symmetricity with respect to the specular position, i.e., J (ω) = J (2θ − ω), which is explained in the literature as a straightforward consequence of the reciprocity theorem, which is often confused with time reversal symmetry [57]. Let us now investigate how our reciprocity formulae can be utilized for this symmetricity property.…”

The reciprocity principle is that, when an emitted wave gets scattered on an object, the scattering transition amplitude does not change if we interchange the source and the detector -in other words, if incoming waves are interchanged with appropriate outgoing ones. Reciprocity is sometimes confused with time reversal invariance, or with invariance under the rotation that interchanges the location of the source and the location of the detector. Actually, reciprocity covers the former as a special case, and is fundamentally different from -but can be usefully combined with -the latter. Reciprocity can be proved as a theorem in many situations and is found violated in other cases. The paper presents a general treatment of reciprocity, discusses important examples, shows applications in the field of photon (Mössbauer) scattering, and establishes a fruitful connection with a recently developing area of mathematics.

“…Conversely, the resonant Mössbauer medium is absorptive and gyrotropic and reciprocity can not be proved to hold in general. 46,59 In fact, the violation of reciprocity in scattering on absorptive and grotropic media is still the subject of both experimental 61,63,64 and theoretical 46,62 works. 60 Nevertheless, for the special case under discussion, when all hyperfine magnetic fields are aligned parallel/antiparallel to the wave vector, one may verify that reciprocity exactly holds.…”

Perturbative theory of grazing-incidence diffuse nuclear resonant scattering of synchrotron radiation

et al. 2007

Theoretical description of off-specular grazing-incidence nuclear resonant scattering of synchrotron radiation (Synchrotron Mössbauer Reflectometry, SMR) is presented. The recently developed SMR, similarly to polarized neutron reflectometry (PNR), is an analytical tool for the determination of isotopic and magnetic structure of thin films and multilayers. It combines the sensitivity of Mössbauer spectroscopy to hyperfine interactions and the depth selectivity of x-ray reflectometry. Specular reflection provides information on the depth profile, while off-specular scattering on the lateral structure of scattering layers. Off-specular SMR and PNR intensity formulae of a rather general multilayer with different domains, based on a Distorted Incident-Wave Approximation (DIWA) are presented. The Distorted-Wave Born Approximation (DWBA) results are given in an Appendix. Physical and numerical implications, why using DIWA, are explained.The temporal character of SMR imposes specific differences between SMR and PNR. In order to reveal the limits of DIWA and to compare the two analytical methods, two-dimensional diffuse SMR and PNR maps of an antiferromagnetic multilayer are calculated and critically compared.
