MEASUREMENT OF 182,184,186W (N, N’ γ) CROSS SECTIONS AND WHAT WE CAN LEARN FROM IT [PDF]
EPJ Web of Conferences, 2021 Today’s development of nuclear installations rely on numerical simulation for which the main input are evaluated nuclear data. Inelastic neutron scattering (n, xn) is a reaction of importance because it modifies the neutron population, the neutron energy

Nuclear data for space exploration
Frontiers in Astronomy and Space Sciences, 2023 Understanding the harmful effects of galactic cosmic rays (GCRs) on space exploration requires a substantial amount of nuclear data. Specifically, the interaction of energetic GCR charged particles with spacecraft materials generates secondary radiations

Absolute measurement of the isotopes 16O and 18O in bombarded H218O sample using deuteron-induced gamma-ray emission technique [PDF]
مجله علوم و فنون هستهای, 2022 In this research work, we used the Deuteron Induced Gamma-ray Emission (DIGE) method based on 18O(d,pγ)19O (Eγ=1376 keV), and 16O(d,pγ)17O (Eγ= 871 keV) nuclear reactions to determine absolute amounts of the stable isotopes 16O and 18O in the irradiated

Search for neutron-hidden neutron interbrane transitions with MURMUR, a low-noise neutron passing-through-walls experiment [PDF]
EPJ Web of Conferences, 2019 Multi-braneworld universe is at the heart of many scenarios of physics beyond the Standard Model and the cosmological model ΛCDM. It is thus an important concern to constrain these scenarios which also allow for experiments below the GeV scale. MURMUR is

Examining the fluorine overabundance problem by conducting Jinping deep underground experiment
He jishu, 2023 BackgroundNuclear reactions have been crucial in the evolution of the universe since the big bang. The cross section of nuclear reaction that occurs during the early evolution of the star is extremely low, so it cannot be accurately measured in a ground ...

s-process Nuclear Reaction Rates [PDF]
EPJ Web of Conferences, 2023 In stars the 13C(α, n)16O and 22Ne(α, n)25Mg reactions are the two main sources of neutrons for the so-called slow neutron capture process (s-process), which is one of the main mechanisms for the stellar synthesis of heavy elements.
