“…Thus, recoil-free nuclear absorption of the gamma radiation (the Mössbauer effect) may appear even for an unbounded free particle. This differs from the results of previous studies of many other smaller objects [24,25]. The specimen studied here should be treated as a set of classical macroscopic absorbers.…”

“…3. Thus, the modified clusters in our case are most likely thick greases rather than colloids, as represented, e.g., by ferric oxide clusters in pores [21], the Mossbauer spectra of which exhibit a superposition of wide and narrow components in contrast to our findings. The mechanism of the influence of the surfactant on 7-ferric oxide clusters will be discussed elsewhere.…”

“…When the M6ssbauer probe is used, its mobility is mainly determined by the microstructure rather than the mobility of the net of the solvated ion exchanger. 5,6 Therefore, an alternative approach is very important: the study of the dynamics of a polymer--water (solvate) system by the Rayleigh scattering of M~ssbauer radiation (RSMR). The possibility to study any substance in the absence of M6ssbauer atoms is a great advantage of the method, although there is some uncertainty in separating the contributions of components of the two(multi)-component system to the integral spectrum of the scattered radiation.…”
