Microscopic Theory for Spontaneous Fission

Frontiers in Physics, 2020
Nuclear fission is a fascinating field of research that involves large-amplitude collective dynamics of a microscopic many-body system. Specifically, the process of spontaneous-fission decay can only be explained within the quantum tunneling phenomenon ...

Structure of the prompt neutron multiplicity distribution in the spontaneous fission of 256Rf

Physics Letters B, 2023
An experimental study of 256Rf spontaneous fission following the fusion reaction of 50Ti+208Pb was performed using the velocity filter SHELS of the Flerov laboratory at JINR. The average number of neutrons of ν‾=4.30±0.17 and variance of σν2=3.2 from the

Manifestation of ternary clusterization in binary spontaneous fission of 252Cf

Physics Letters B
New ternary cluster mode in binary fission is suggested. This abnormal binary decay is characterized by a much lower total kinetic energy, a much higher excitation energy of heavy fission fragment and, thus, a larger neutron multiplicity.

Spectral averaged cross sections as a probe to a high energy tail of 235U PFNS [PDF]

EPJ Web of Conferences, 2023
The systematic evaluations of spectrum averaged cross sections of dosimetric reactions over a broad range of energies were performed in 252Cf (spontaneous fission) and 235U(nth,f) neutron fields.

Method to Compare Fission-to-Scattering Ratios using Uranium-238 [PDF]

EPJ Web of Conferences, 2023
A novel method was developed to separate the 238U fission contribution measured in quasi-differential time-of-flight scattering experiments in order to isolate the elastic and inelastic events.

A Study of the Minimum Thermal Power of a Nuclear Reactor

Journal of Nuclear Engineering, 2021
The minimum mass for a critical reactor is well studied whereas the minimum heat production from a nuclear reactor has received little attention. The thermal power of a (sub)critical reactor originates from fission as well as radioactive decay.

Investigation of the spontaneous fission properties of neutron-deficient nobelium isotopes

Eurasian Journal of Physics and Functional Materials, 2021
In the last years we carried out several experiments aimed to investigate properties of short-lived SF isotopes. The neutron-deficient isotopes of nobelium were produced in fusion-evaporation reactions using206,208Pb targets and an intense48Ca-beam ...
