Nuclear data activities at the n_TOF facility at CERN
(2016-10-21)
Nuclear data in general, and neutron-induced reaction cross sections in particular, are important for a wide variety of research fields. They play a key role in the safety and criticality assessment of nuclear technology, ...
Be 7 (n,α) He 4 Reaction and the Cosmological Lithium Problem : Measurement of the Cross Section in a Wide Energy Range at n-TOF at CERN
(2016-10-03)
The energy-dependent cross section of the Be7(n,α)He4 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 ...
Recent results in nuclear astrophysics at the n-TOF facility at CERN
(2016-09-11)
The neutron time of flight (n-TOF) facility at CERN is a spallation source characterized by a white neutron spectrum. The innovative features of the facility, in the two experimental areas, (20 m and 185 m), allow for an ...
Integral measurement of the 12C(n, p)12B reaction up to 10 GeV
(2016-04-22)
The integral measurement of the 12C(n, p)12B reaction was performed at the neutron time-of-flight facility n_TOF at CERN. The total number of 12B nuclei produced per neutron pulse of the n_TOF beam was determined using the ...
Towards the high-accuracy determination of the 238U fission cross section at the threshold region at CERN - N-TOF
(EDP Sciences, 2016-03-15)
The 238U fission cross section is an international standard beyond 2 MeV where the fission plateau starts. However, due to its importance in fission reactors, this cross-section should be very accurately known also in the ...
Fission Fragment Angular Distribution measurements of 235U and 238U at CERN n-TOF facility
(EDP Sciences, 2016-03-15)
Neutron-induced fission cross sections of 238U and 235U are used as standards in the fast neutron region up to 200 MeV. A high accuracy of the standards is relevant to experimentally determine other neutron reaction cross ...
