Shell effects and the neutron emission within the multi-dimensional Langevin model for nuclear fission

F. A. Ivanyuk, S. V. Radionov, C. Ishizuka +1

We solve the Langevin equations for the time evolution of parameters that describe the shape of fissioning system. On each integration step, we calculate the probability of neutron…

Shell effects and multi-chance fission in the sub-lead region

F. A. Ivanyuk, C. Schmitt, C. Ishizuka +1

Within the recently developed five-dimensional Langevin approach for the description of fission of heavy nuclei, we have calculated the fission fragments mass and kinetic energy di…

Dumbbell shapes in the super-asymmetric fission of heavy nuclei

F. A. Ivanyuk, N. Carjan

We have calculated the fission fragments' mass distributions for several isotopes of heavy and super-heavy nuclei from uranium to flerovium within an improved scission point model.…

The Langevin approach for fission of heavy and super-heavy nuclei

F. A. Ivanyuk, S. V. Radionov, C. Ishizuka +1

In this contribution, we present the main relations of the Langevin approach to the description of fission or fusion-fission reactions. The results of Langevin calculations are sho…

Dependence of total kinetic energy of fission fragments on the excitation energy of fissioning systems

Kazuya Shimada, Chikako Ishizuka, Fedir A. Ivanyuk +1

We elucidated the reason why the average total kinetic energy (TKE) of fission fragments decreases when the excitation energy of the fissioning systems increases as indicated by ex…

Memory effects in Langevin approach to the nuclear fission process

F. A. Ivanyuk, S. V. Radionov, C. Ishizuka +1

We present the schematic calculations within the Langevin approach in order to investigate the dependence of fission width on the memory time and the excitation energy at low tempe…

Fission of super-heavy elements: Sn-plus-the-rest, or Pb-plus-the-rest ?

C. Ishizuka, X. Zhang, M. D. Usang +2

In this work we try to settle down the controversial predictions on the effect of doubly magic nuclei Sn and Pb on the mass distributions of fission fragments of su…

Description of the mass-asymmetric fission of the Pt isotopes, obtained in the reaction Ar + Nd within the two-stage fusion-fission model

V. L. Litnevsky, F. A. Ivanyuk, G. I. Kosenko +1

The two stages dynamical stochastic model developed earlier for description of fusion-fission reactions is applied to the calculation of mass- and energy-distributions of fission f…

Fission of super-heavy nuclei: Fragment mass distributions and their dependence on excitation energy

N. Carjan, F. A. Ivanyuk, Yu. Ts. Oganessian

The mass and total kinetic energy distributions of the fission fragments in the fission of even-even isotopes of superheavy elements from Hs (Z=108) to Og (Z=118) are estimated usi…

Correlated transitions in TKE and mass distributions of fission fragments described by 4-D Langevin equation

M. D. Usang, F. Ivanyuk, C. Ishizuka +1

We have decomposed to symmetric and asymmetric modes the mass-TKE fission fragment distributions calculated by 4-dimensional Langevin approach and observed how the dominant fission…

The temperature dependence of the shell corrections

F. A. Ivanyuk, C. Ishizuka, M. D. Usang +1

We have examined the dependence of the shell correction to the nuclear liquid drop energy at finite excitations on the excitation energy (temperature). For this we have calculated…

Analysis of the total kinetic energy of fission fragments with the Langevin equation

Mark Dennis Usang, Fedir Ivanyuk, Chikako Ishizuka +1

We analyzed the total kinetic energy (TKE) of fission fragments with three-dimensional Langevin calculations for a series of actinides and Fm isotopes at various excitation energie…

A 4-dimensional Langevin approach to low-energy nuclear fission of U

Chikako Ishizuka, Mark D. Usang, Fedir A. Ivanyuk +3

We developed a four-dimensional Langevin model which can treat the deformation of each fragment independently and applied it to low energy fission of 236U, the compound system of t…

To fission or not to fission

Krzysztof Pomorski, Bozena Nerlo-Pomorska, Fedir A. Ivanyuk

The fission-fragments mass-yield of 236U is obtained by an approximate solution of the eigenvalue problem of the collective Hamiltonian that describes the dynamics of the fission p…

The Scission-Point Configuration within the Two-Center Shell Model Shape Parameterization

F. A. Ivanyuk, S. Chiba, Y. Aritomo

Within the two-center shell model parameterization we have defined the optimal shape which fissioning nuclei attain just before the scission and calculated the total deformation en…

On the Scission Point Configuration of Fisioning Nuclei

Fedir Ivanyuk

The scission of a nucleus into two fragments is at present the least understood part of the fission process, though the most important for the formation of the observables. To inve…
