Table 1

A list of unc. sources typically encountered in (n,f) fission cs measurements is provided together with a range of unc., their correlations, and comments on possible cross-correlations between unc. of different experimental datasets as a rough estimate if no information is provided for a specific experiment.

Unc. source Typical range Cor(Expi, Expi) Cor(Expj, Expj) i ≠ j
Sample mass >1% Full ≠ 0 if same sample used
Counting statistics Sample and measurement time-dependent Diagonal 0
Attenuation 0.02%–2% Gaussian Likely
Detector efficiency 0–0.3%, 1%–2% Full < 10 MeV Likely, 0.5–1
FF angular distribution ≈ 0.1% Gaussian Likely, 0.75–1.0
Background 0.2–>10% Gaussian Possible
Energy unc. 1%, 1–3 ns From conversion Technique-dependent
Neutron flux 0%, >1% 0.5–Full Technique-dependent
Multiple scattering 0.2%–1% Gaussian 0.5–0.75
Impurities in the sample Sample-dependent 0.9–1 0.5–0.75
Dead time >0.1% Full 0

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
