The monograph describes the properties of the lightest nuclei with large excess of neutrons. The results of theoretical and experimental studies of neutron-rich isotopes with 1 Z 20 are presented while also changes in the structure of nuclei when going away from the line of -stability are discussed. Information presented is on the mass, radii of distribution of nuclear matter, energy levels for excited states of these nuclei, the possibility of manifestation of a halo, as well as the deformation of nuclei and the quantum properties of ground states. The position of the boundary of nucleon stability for these nuclei is considered. The effects associated with weakening and even the disappearing influence of standard magic numbers and the appearance of new ones are discussed.The results presented in the book will be useful in other fields of science as well, including astrophysics.

This is the proceedings of the Ninth International Symposium on Exotic Nuclei EXON-2018, 10-15 September, Petrozavodsk, Russia. The first symposium took place 27 years ago in 1991 in Foros (Crimea), the later symposiums were held on Baikal Lake, in Peterhof, Khanty-Mansiysk, Sochi, Vladivostok, Kaliningrad and Kazan. The organizers of the Symposium were the five largest scientific centers of heavy-ion physics - JINR (Dubna), the RIKEN Research Center (Japan), the GANIL National Center (France), the GSI Helmholtz Centre for Heavy Ion Research (Germany), the National Superconducting Cyclotron Laboratory (Michigan, USA). The main topics are: properties of light exotic nuclei, synthesis and properties of superheavy elements, rare processes and decays, experimental facilities and future projects.

The symposium was held at Kazan, Russia from 4 - 10 September 2016. EXON-2016 was dedicated to the problems of producing and investigating nuclei far from the line of stability.The main goal of the symposium was to discuss the latest results on the production and study of the properties of the lightest to the heaviest nuclei, as well as the plans for future joint investigations in the field of exotic nuclei. The talks were presented by leading scientists in the field. Among the topics of the symposium were the following: production and study of properties of nuclei in extreme states, strongly deformed nuclei, highly excited and nuclei far from the line of stability as well as nuclei having large angular momenta. New results of the investigations are presented in this book. In particular, the latest results on the synthesis of new superheavy elements are also presented. There were also talks devoted to existing detecting devices and accelerators of exotic nuclei as well as to the future projects for the creation of similar set-ups.

The production and the properties of nuclei in extreme conditions, such as high isospin, temperature, angular momenta, large deformations etc., have become the subject of detailed investigations in all scientific centers. The main topics discussed at the Symposium were: Synthesis and Properties of Exotic Nuclei; Superheavy Elements; Rare Processes, Nuclear Reactions, Fission and Decays; Experimental Facilities and Scientific Projects.This book provides a comprehensive overview of the newest results of the investigations in the main scientific centers such as GSI (Darmstadt, Germany), GANIL (Caen, France), RIKEN (Wako-shi, Japan), MSU (Michigan, USA), and JINR (Dubna, Russia).
