Performance of the neutron time-of-flight facility n_TOF at CERN

Carlos Guerrero, +116 more
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.
Journal ArticleDOI

New Measurement of the Fe 60 Half-Life

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.

7Be(n, p)7Li Reaction and the Cosmological Lithium Problem: Measurement of the Cross Section in a Wide Energy Range at n_TOF at CERN

Mario Barbagallo, +133 more
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.
