1974Kr27
E
~0.2 keV
(or worse)
I
~5%
(or worse)
Data from two main references : 1974Kr27 and 1973Fe08
Decay Scheme Rather Well Established
Recent measurement to be incorporated
Uncertainties well documented
GTOL is not happy
How to combine these measurements?
•
Must adopt the newer Krane values ??
•
Weighted average has no impact here
•
What about merging in the Adopted Values??
•
Arbitrarily increase uncertainties?

In this data-driven analysis, the status of 83Se decay is examined based on references from 1974 and 1973. The decay scheme is well established, with recent measurements incorporating uncertainties at a remarkably low level. The documentation of uncertainties is thorough. However, challenges arise regarding how to combine these diverse measurements effectively - whether to adopt newer values, merge in adopted values, or adjust uncertainties. This comprehensive examination aims to provide clarity on deriving precise conclusions from the available data.

Status of 83Se decay, prior to 2015 Data from two main references : 1974Kr27 and 1973Fe08 1974Kr27 E ~0.2 keV (or worse) I ~5% (or worse)
Recent measurement to be incorporated Uncertainties as low as E = 0.01 keV I ~ 1%
How to combine these measurements? Must adopt the newer Krane values ?? Weighted average has no impact here What about merging in the Adopted Values?? Arbitrarily increase uncertainties?
