TL;DR: In this paper, the energy spectrum of prompt neutrons emitted in fission (PFNS) plays a very important role in nuclear science and technology, and a Coordinated Research Project (CRP) was established by the IAEA Nuclear Data Section in 2009, with the major goal to produce new PFNS evaluations with uncertainties for actinide nuclei.
Journal ArticleDOI
Definitions of radioisotope thick target yields
Naohiko Otuka,Sandor Takacs +1 more
TL;DR: In this paper, the definitions of thick target yields are reviewed in relation to their documentation for the experimental nuclear reaction data library (database) in order to compile them in the experimental data library in a consistent manner, and also to properly utilise them for comparison with other experimental and evaluated yields.

TL;DR: The CIELO collaboration as discussed by the authors studied neutron cross sections on nuclides that significantly impact criticality in nuclear technologies with the aim of improving the accuracy of the data and resolving previous discrepancies in our understanding.
Journal ArticleDOI
