AbstractAbstract
[en] A new approach to the interpretation of the process of spontaneous fission of heavy nuclei is suggested. It is based on nuclear physics data which are obtained in heavy-ion collisions. The process of spontaneous fission consists of three sequential stages: clusterization of the valent nucleons of a heavy nucleus into a light nucleus-cluster, which leads to the formation of a dinuclear system; evolution of the dinuclear system which proceeds by nucleon transfer from the heavy to light nucleus; and decay of the dinuclear system from the equilibrium configuration into two fragments.

Предлагается новый подход к интерпретации процесса спонтанного деления тяжелых ядер, который опирается на данные, полученные в ядерно-физических исследованиях с тяжелыми ионами. Спонтанное деление включает в себя три последовательно протекающие стадии: кластеризацию валентных нуклонов тяжелого ядра в легкое ядро-кластер, в результате чего возникает двойная ядерная система; эволюцию двойной ядерной системы, протекающую путем передачи нуклонов от тяжелого к легкому ядру, и распад двойной системы из равновесной конфигурации на два ядра-осколка.Primary Subject

AbstractAbstract
[en] Here, the structure of decoupled positive-parity and semidecoupled negative-parity bands up to high spin in 197,199Hg has been studied using multinucleon transfer reactions with the Gammasphere array. A positive-parity band in 199Hg with the (vi13/2)3 decoupled configuration that deexcites to levels in the negative-parity sequences is newly established. The semidecoupled sequences in both isotopes are extended to higher spin. Rotation-aligned angular momenta and crossing frequencies determined from experiment are in fair agreement with those from cranking calculations. Finally, a transition from oblate collective rotation at low spin to triaxial noncollective shapes at high spin is indicated.

AbstractAbstract
[en] Nuclear processes that influence the final fission fragment spins and excitation energies are important from a nuclear technology view-point because they determine the partition and energy release through prompt neutrons and gamma rays. From a fundamental view-point too they are very important and they still constitute a widely open problem in collective nuclear dynamics. These processes are caused by motions of nucleons governed by the changing one-body mean field. Keeping this in mind, the present work examine the fragment spin bearing modes that are active during the final phases of the fission process

AbstractAbstract
[en] The detection of multinucleon transfer channels populated with very low cross-sections allow to study into detail phenomena that are important for a wide class of experiments. Some of the results recently obtained at LNL with the time-of-flight magnetic spectrometer PISOLO are discussed. A comparison between the data and the microscopic calculations performed with the new theoretical model developed by the Copenhagen group are presented

AbstractAbstract
[en] Nuclear K-isomers play an important role in understanding the structure of deformed axially symmetric nuclei. Examples are presented of recent studies in the rare-earth region (A ∼ 180) using deep-inelastic and multi-nucleon transfer reactions, and in the trans-fermium region (A ∼ 250) using fusion-evaporation reactions. A specific two-level mixing scenario is invoked to explain the unusual decay of the Kπ = 13+ isomer in 174Lu. The identification of 2- and 4-quasiparticle isomers in 254No is discussed and predictions of similar isomers in neighboring No and Rf nuclei are presented.
