This paper presents the phenomenon of directed nuclear radiation based on the analysis of Lobachevsky angle of parallelism. In spite of the wide application of Lobachevsky geometry in relativistic physics [1-3], one of its basic concepts, the angle of parallelism, has not received due interpretation. The angle of parallelism characterizes the closeness of a produced particle to the absolute in ...

Radiation-induced metabolic changes previously observed in tumors using phosphorus nuclear magnetic resonance spectroscopy include changes in the relative amounts of the phospholipid precursors phosphoethanolamine and phosphocholine, increases in membrane catabolites, and increases in energy status. To elucidate the degree to which these in vivo alterations are a result of intrinsic cellular ch...

Numerous applications of M\"ossbauer spectroscopy are related to a unique resolution absorption spectra resonant radiation in crystals, when the nucleus absorbs photon without recoil. However, narrow nuclear linewidth renders efficient driving nuclei challenging, restricting precision spectroscopy, inelastic scattering and quantum optics. Moreover, need for dedicated x-ray optics restricts acce...

We have experimentally characterized the light-output response of a deuterated trans-stilbene (stilbene-d12) crystal to quasi-monoenergetic neutrons in 0.8 4.4 MeV energy range. These data allowed us perform neutron spectroscopy measurements DT 14.1 source and 239PuBe by unfolding impinging spectrum from measured response. The stilbene-d12 outperforms 1H−stilbene similar size when comparing sha...

The goal of this project is to examine the potential for using optical spectroscopy techniques, such as UV-Visible Spectroscopy and Laser Fluorescence Spectroscopy, for special nuclear materials accountability applications for the UREX+ and other solvent extraction processes. To increase the inherent proliferation resistance of the solvent extraction process, it is necessary to develop on-line ...
