Dr. Yuri Penionzhkevich will be participating at the International Conference on Atomic & nuclear Physics held by Scientific Federation. Professor . Yuri Penionzhkevich is invited as Speaker for this conference. Professor Yu. E. Penionzhkevich works at the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research since 1965 after graduating from the Faculty of Physics of the Voronezh State University. He is a leading scientist in the field of atomic and heavy ion physics. With his participation, many important results were obtained for the first time on the mechanism of heavy-ion induced reactions, on the synthesis and properties of new nuclei close to the limits of stability. Under his supervision new physical setups were designed and put into operation at the beams of the heavy ion cyclotrons in Dubna, as well as for joint experiments at heavy ion beams provided in world centers like GANIL (France), VICKSI (Germany), RIKEN (Japan), CL (Finland). In 1968 a series of investigations on the fission of heavy nuclei was awarded the State Premium for young scientists. Yu.Penionzhkevich is the co-author of the discovery of the new element 106 of the Mendeleev Periodic Table.Starting in 1979 up till now he is the head of a scientific department in the Flerov Laboratory of Nuclear Reactions, where several fundamental results were obtained on the synthesis and properties of exotic nuclei. From 1989 till 1997 he was scientific deputy director of the Laboratory. Professor Yu. E. Penionzhkevich is a well-known scientist. He has been elected in the Council of the National Center GANIL .
Dr Yu. E. Penionzhkevich is going to talk on EXOTISM OF NUCLEI Synthesis and study of neutron-rich isotopes have two main goals finding the position of neutron stability boundaries and obtaining data on properties of exotic nuclei near these boundaries. The development of accelerator technology has made it possible to obtain the accelerated beams of secondary radioactive nuclei. In this connection, new vast opportunities have opened up for studying both the structure of light exotic nuclei themselves and the peculiarities of nuclear reactions induced by these nuclei. It is extremely important to obtain new information regarding nuclei near the nucleon stability boundary because considerable deviations of properties of such nuclei from the widely known regularities may be expected (and are already observed). Here the nuclei in a range of small Z serve as convenient objects for investigation. However, the question of how general the corollaries made for this small number of nuclei is crucial. The experiment alone can give an answer to this question.
The present work reviews the properties of the super neutron-rich isotopes. The changes in nuclear structure appearing as one goes away from the β-stability line are discussed in detail. Information is presented on the mass (hence, on the separation energy of nucleons and on nuclear stability), the radii of nucleon distributions, the momentum distributions of fragments from the break-up of neutron-rich nuclei, on the possibility of halo formation as well as on the deformation and quantum characteristics of the ground states of different isotopes. The location of the neutron drip line and questions about the stability of nuclides are considered in connection with the weakening or even vanishing of the shell effects at the magic numbers 20 and 28, and the discovery of the new neutron magic number.
ICANP-2018 brings along leading scientists, engineers, administrators of firms within the scope of Atomic & physics to exchange data on their current analysis progress. ICANP-2018 has initiated with an excellent Organizing Committee from well-known universities across the world, creating it a specially designed cluster conference which will be covering most aspects and fields of Atomic & physics.
