A recently developed theoretical model for the fission fragment yield
distributions, based on the nuclear energy density functional theory, will be
elaborated. The model is further extended to account for the odd-even staggering
in the fission fragments' charge yields. The predicted results for preactinides,
actinides, and superheavy nuclei will be presented and compared with the...
The reaction mechanisms have been investigated intensively in many
reactions with heavy ions. Several processes can take place at the interaction of
two colliding nuclei. The main of them are fusion-fission, quasifission, fast fission,
multinucleon transfer, the formation of the evaporation residue, deep inelastic
collisions and, finally, quasielastic and elastic scattering. A big set of...
In the present study, an overview of different reaction mechanisms
involved light and heavy ion induced reactions has been investigated at low
energies below 10 MeV/nucleon. In light ion reactions, an intermediate mechanism
so called pre-compound (PCN) emission which is bridging between compound
(CN) and direct reactions (DR) is attracted significantly due to its interplay between
nuclear...
The knowledge of the
optimal collision energies at synthesis of the new superheavy elements and of the
contributions of products formed in different reaction channels to the mixed mass
distributions measured in the experiments are of the interest of experimenters. The
dinuclear system (DNS) model \cite{} developed in cooperation between
researchers of the Joint Institute for Nuclear...
When two massive nuclei collide, the reaction leads to the capture of the
heavy-ion projectile into the heavy target nucleus and forms a dinuclear system
after the collision. The system goes through a large-scale collective rearrangement
of the nucleonic matter and develops into an equilibrated compound nucleus (CN),
known as the complete fusion process. However, if the dinuclear system...
Present
work provides a review about experiments carried out with separators GRAND
[1-2] and SHELS [3-4]. The latter is a modernization of the kinematical electrostatic
separator VASSILISSA [5–6]. GRAND is a new gas-filled separator designed to
operate with high-intensity beams delivered by the cyclotron DC-280. It was
constructed within the framework of the SHE Factory project [7] in...
Nowadays applying of multinucleon transfer reactions (MNT) in heavy
nuclei collisions is supposed as a promising approach to produce new heavy and
superheavy nuclei, especially neutron-rich nuclei. The investigation of their
properties is very important for understanding of nucleosynthesis processes. To
reach the «island of stability» the use of heavy systems such as 238U + 238U and
238U...
We analyse the binding energy and charge distribution radius for the
latest superheavy nuclei synthesized in various laboratories, with atomic numbers
$Z=110-118$. For this calculation we use extended Thomas-Fermi approximation
within the relativistic mean field framework. The binding energy and radii are
compared with the results obtained from relativistic Hartree calculations along...
Exotic nuclei are typically produced via projectile fragmentation or
projectile fission at relativistic energies, or through complete fusion reactions at
near-Coulomb barrier energies. These production methods, along with the
available beam intensities, define the current boundaries of the chart of nuclides.
However, theoretical predictions suggest that several thousand additional...
The advent of high-efficiency gamma ray spectrometers with multiple
types of detectors, digital-signal-processing based data acquisition system, and
the realistic possibility of taking a stride in the hitherto unknown territory of nuclear
landscape are driving the low- and medium-energy nuclear physics into the path of
exciting exploration. With this in consideration, a novel facility,...
An experimental study to elucidate the fusion fission dynamics from a
series of nuclear reactions with 40Ar beam at near barrier energies have been
carried out at the K500 cyclotron at VECC, Kolkata. The role of the deformed 40Ar
projectile on a series of targets of 206Pb and 208Pb was examined in this study.
The main motivation was to study the competition between quasi-fission and...
The Hoyle state (Ex = 7.654 MeV, Jπ = 0+) in 12C plays a central role in
stellar nucleosynthesis, serving as the resonant gateway for carbon formation
through the triple-alpha process. Despite its well-established sequential decay via
the ground state of 8Be, the rare possibility of direct three-alpha (DD) decay
remains a key probe of its underlying alpha-cluster. In this work, we explore...
Unlike the other reaction mechanisms, nuclear fission process leads to
the production of a large number of fission fragment nuclei. As a result, very
complicated in-beam gamma ray spectra are obtained from the experiment based
on fission fragment spectroscopic measurement. Hence, a very careful and
thorough analysis procedure is to be adopted for extracting different features
related to...
The study of nuclear reactions across different energy domains provides
valuable insights into nuclear structure, dynamics, and the equation of state of
nuclear matter. At low energies, reactions are dominated by mean-field effects,
whereas at very high energies, nucleon–nucleon collisions can produce
quark–gluon plasma. In the intermediate energy regime (20 MeV/nucleon to 2
GeV/nucleon),...
