Delayed gamma-ray spectroscopy combined with active neutron interrogation for nuclear security and safeguards

EPJ Web of Conferences, 2017
For the purpose of nuclear security and safeguards, an active neutron interrogation non-destructive assay technique, Delayed Gamma-ray Spectroscopy (DGS), is under development. The technique of DGS uses the detection of decay γ rays from fission products

Total absorption γ-ray spectroscopy measurements at GANIL with STARS [PDF]

EPJ Web of Conferences
The Total Absorption γ-ray Spectroscopy technique allows for a precise determination of the β-decay strength free from the Pandemonium systematic error. Currently, a new-concept hybrid spectrometer, STARS, is under development within the framework of the

A first glimpse at the shell structure beyond 54Ca: Spectroscopy of 55K, 55Ca, and 57Ca

Physics Letters B, 2022
States in the N=35 and 37 isotopes 55,57Ca have been populated by direct proton-induced nucleon removal reactions from 56,58Sc and 56Ca beams at the RIBF. In addition, the (p,2p) quasi-free single-proton removal reaction from 56Ca was studied.

Ground-state β-feeding determination using total-absorption spectrometers

Frontiers in Physics
The determination of the β intensity probability between the ground states of parent and daughter nuclei has traditionally been a difficult task with standard γ-spectroscopy approaches due to the lack of the associated γ emission.

Restoration of the natural E(1/21+) - E(3/21+) energy splitting in odd-K isotopes towards N = 40

Physics Letters B, 2020
We report on the first γ-ray spectroscopy of 51,53K produced via the 52,54Ca(p,2p) reactions at ∼250 MeV/nucleon. Unambiguous final-state angular-momentum assignments were achieved for beam intensities down to few particles per second by using a new ...

Correlation between Emission-line Luminosity and Gamma-Ray Dominance in the Blazar 3C 279

The Astrophysical Journal, 2023
Despite numerous studies, the origin of the γ -ray emission from blazars is still debated, in particular whether it is produced by leptonic or hadronic processes.

Using CGMF to estimate corrections for fission yields measured via γ-ray spectroscopy [PDF]

EPJ Web of Conferences, 2020
Fission product yields have been inferred using γ-ray spectroscopy for several decades. Typically, these efforts have focused on even-Z even-A fission products as their nuclear structure are less complicated.

Spectroscopy of neutron rich nuclei using cold neutron induced fission of actinide targets at the ILL: The EXILL campaign

EPJ Web of Conferences, 2013
One way to explore exotic nuclei is to study their structure by performing γ-ray spectroscopy. At the ILL, we exploit a high neutron flux reactor to induce the cold fission of actinide targets.
