Nuclear Spectroscopy Department

(Head – Dr. Sci. V. T. Kupryashkin)

Department was found in 1965 by G. D. Latyshev, Corresponding Member of the Academy of Sciences of Ukrainian SSR. From 1973 to 1990 department was headed by Professor A. I. Feoktistov.

Main directions of scientific activity:

• Experimental investigations of radioactive decay by means of magnetic β- and γ-spectrometers.
• Shaking mechanism study.
• High energy physics. Investigation of spectra and decay of high energy soliton objects of D-brane type.
• Investigation of near- zero energy electrons (E ~ 1 eV).

The most important scientific results:

·        High resolution magnetic beta-spectrometer was created.

• Precision measurements of energies and intensities of the conversion and Auger electrons were carried out.
• New data about penetration effect in nuclear conversion for some forbidden gamma-transitions in deformed nuclei were obtained.
• A new method of the lifetime measurements of excited nuclear states from the thermal neutron (n, γ)-reactions by means of Dopler shift attenuation was developed.
• Energy spectra of BPS-states and possible D-brane decay channels were studied by means of modern theories (K-theory, algebraic geometry and homological algebra).
• The main properties of near- zero energy electrons from radioactive decay were investigated.
