SEMINAR

Topic: Observation and Mechanism of Synthesis of Unknown Superheavy Nuclei in Kiev "Proton-21" Lab and the problem of Stability of the Matter

Speaker: Prof. V.I. Vysotskii, Kiev National Shevchenko University and Proton-21 Lab

Date & Time: Thursday, January 26, 2006, 1:00 PM

Place: Room 140 VMC (Chambers Hall)

ABSTRACT

 

Pioneering results on the creation of the stable superheavy nuclei with A >300-400 using unique pulsed electron-beam driver (developed in the Kiev's Proton-21 Lab) will be discussed. The total number of created superheavy nuclei in each experiment are more that 1013 -1014. The total number of experiments exceeds 10000. The problem of stability of usual (atomic) form of matter is discussed. The theory and possible mechanisms of creation of stable and quasistable superheavy nuclei are presented. The brief history and the main results of Kiev Proton-21 lab activities are presented. The mechanism of nuclear transmutatiom is connected with realization of controlled collapse state of electron-nuclear system in the volume of the target. The main part of the presentation is connected with the results of experimental and theoretical investigation of superheavy nuclei that were obtained in Proton-21 lab. The experiments on utilization of radioactive waste with any kind of activity to stable nuclei during the process of transmutation of nuclei in the volume of the collapse are also discussed. The effectiveness of radioactive waste utilization is about 10-20% in the single action (about 1019 transmutated radioactive nuclei to nonradioactive ones per 1 J of input energy of the driver).

BIOGRAPHICAL SKETCH

 

Prof. V.I. Vysotskii received his PhD (theoretical Physics) from Kiev Institute of theoretical physics of Ukrainian Academy of Science in 1975. He has also received the additional Habilitus degree in Theoretical Physics, and Solid State physics from Kiev National Shevchenko University in 1992. Since 1992 he has been a Full Professor in the Kiev National Shevchenko University. His research interest include topics in laser Physics (including X-Ray and Gamma-Ray lasers), Nuclear Physics - creation of abnormal nuclei, stability of nuclear matter, nuclear fusion, Nuclear Astrophysics - neutron and proton stars, Supernova gravitation collapse, biophysics. Prof. Vysotskii has published more than 150 articles in referred journals, including three books: 1-Gamma-Ray Lasers (1989), 2- Nuclear Fusion and transmutation of Isotopes in Biological Systems, (2003), 3- Introduction to Biophysics of Activated Water, (2005).

Refreshments will be served at 12:45 PM
