Mößbauer Spectroscopy

The number of 61Ni Mössbauer studies, although small, indicates that definitive measurements are possible once experimental obstacles have been overcome. The experimental method and hyperfine interactions in 61Ni are discussed briefly, followed by a review of results obtained from 61Ni Mössbauer experiments during the last 10 years. The results are discussed in relation to the determination of spin structures, the study of electronic transitions, and the study of hyperfine interactions.

Abstract In this paper, we present the results of the propagational dynamics of vortex beams in the scope of their possible applications for interferometric non-contact robust and precision optical surface profilometry with nanoscale longitudinal resolution. The result of coaxial superposition of the reference plane wave with singly charged vortex beams represents a dynamically changing intensity distribution. The nature of this changes, namely, rotational effects of intensity zeros, allows to determine directly the optical path difference which is introduced by the surfaces and internal structure of test object. We have proposed the experimental setup for examination of reflecting and transmitting objects.
