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 β-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.

It is known that nuclear shells play a particularly important role in the collective motion of nuclear matter and, as a consequence, determine the structure of nuclei, nuclear dynamics, nuclear decay models, etc.In 1999 the nuclear shell model turned fifty, and the 49th meeting on Nuclear Spectroscopy and Nuclear Structure was devoted to nuclear shells in their various manifestations. The talks presented at the conference covered a wide range of experimental and theoretical studies.

This book presents recent results on experimental and theoretical studies of the interaction of heavy ions with nuclei at low and intermediate energies: the dynamics of fusion and decay of complex nuclear systems, the synthesis of superheavy elements, the synthesis and properties of exotic nuclei close to the proton and neutron driplines, nuclear fission, nuclear structure, and reactions with stable and radioactive ion beams. It also covers some aspects of applied physics research: track membranes and their applications, the use of polymers in medicine and electronics, production and application of radioisotopes for medical purposes, and environmental protection.

The proceedings of the conference include recent results of experimental and theoretical research on the following topics: reaction dynamics, fusion-fission phenomena, neutron physics, deformed shells, nuclear spectroscopy, and exotic nuclei.
