Prompt neutrons accompanying the spontaneous fission of $^{250}$No [PDF]

, 2023
International audienceThis paper describes the experiment conducted on the SHELS (Separator for Heavy Element Spectroscopy) separator [1] aimed at studying the properties of spontaneous fission of 250No. A separator detection system consists of a time-of-

Measurement of the prompt fissionγ-ray spectrum of 242Pu

EPJ Web of Conferences, 2018
The prompt γ-ray spectrum of fission fragments is important in understanding the dynamics of the fission process, as well as for nuclear engineering in terms of predicting the γ-ray heating in nuclear reactors.

Experimental information on mass- and TKE-dependence of the prompt fission γ-ray multiplicity

Physics Letters B, 2021
Prompt γ rays from the spontaneous fission of 252Cf were measured with cerium-doped LaBr3 detectors. The average prompt fission γ-ray multiplicity, Mγ, was determined as a function of fragment mass number (A) and total kinetic energy (TKE).

Neutrons from spontaneous fission of long‐lived super‐ heavy nuclei [PDF]

, 2009
International audienceThe investigations of spontaneous fission of 268Db (Z = 105) have been performed. 268Db is the heaviest nuclide for which the average number of neutrons per spontaneous fission math = 4.2±1.0 was measured.

Systematic measurements of prompt fission γ rays – and what they tell us about fission fragment de-excitation [PDF]

EPJ Web of Conferences, 2019
In a recent measurement of prompt γ rays from the spontaneous fission of 252Cf an experimental setup was chosen that allowed the study of angular correlations between γ rays and the nuclei from which they were emitted.

SPONTANEOUS FISSION HALF-LIVES IN VARIOUS MACROSCOPIC-MICROSCOPIC MODELS [PDF]

, 2011
The problem of describing spontaneous fission for the entire region of superheavy nuclei is continually present in theoretical investigations. This study outlines the results of the calculations of fission barriers and spontaneous fission half-lives for

Prompt fission gamma-ray emission spectral data for 239Pu(n,f) using fast directional neutrons from the LICORNE neutron source

EPJ Web of Conferences, 2018
Prompt fission gamma-ray spectra (PFGS) have been measured for the 239Pu(n,f) reaction using fast neutrons at Ēn=1.81 MeV produced by the LICORNE directional neutron source.

Parameter Optimization and Sensitivity Studies of Spontaneous Fission with FREYA [PDF]

EPJ Web of Conferences, 2020
For many years, the state of the art for simulating fission in transport codes amounted to sampling from average distributions. However, such "average" fission models have limited capabilities.
