TL;DR: In this paper, the authors present the characteristics of the new neutron beam in the currently available configurations, which correspond to two different collimation systems and two choices of neutron moderator, including the intensity and energy dependence of the neutron flux, the spatial profile of the beam, the in-beam background components and the energy resolution/broadening.

TL;DR: In this paper, a new determination of the half-life of the radioactive isotope $60{Fe}$ using high precision measurements of the number of atoms and their activity in a sample containing over ${10}^{15}$ $^{60}$ atoms was made, which has significant implications for interpretations of galactic nucleosynthesis and for determinations of formation time scales of solids in the early Solar System.

TL;DR: HolMES as mentioned in this paper is a new experiment to directly measure the neutrino mass using a calorimetric approach as an alternative to spectrometers, which eliminates systematic uncertainties arising from the use of external beta sources.

TL;DR: The energy-dependent cross section of the ^{7}Be(n,α)^{4}He reaction, of interest for the so-called cosmological lithium problem in big bang nucleosynthesis, has been measured for the first time from 10 meV to 10 keV neutron energy.
