Study of Heavy Nuclei at FLNR (Dubna)

Abstract

The synthesis of new nuclides has been performed with the use of the gas-filled recoil separator; in a number of experiments some radio-chemical methods have been employed. The experimental data point to a substantial increase in the nuclear stability with a growing neutron number. For all the nuclei in decay chains undergoing α decay or spontaneous fission the energies and half-lives have been measured. The obtained data are in agreement with predictions of microscopic theory on the deciding role of the nuclear shells in the stability of heaviest elements.
