A new determination of the 68Ga half-life and evaluation of literature data

Inconsistencies within the 68Ga half-life dataset have been repeatedly identified in nuclear decay data evaluations performed over the past decade. In this paper, a half-life has been determined using ionisation chambers measurements and HPGe gamma-ray spectrometry (T1/2 = 67.783(27) min). The current literature has been reviewed and possible causes of discrepancy have been identified, such as neglected contaminant effects, robustness of analysis, and underestimation of systematic effects. This could lead to a significant improvement of the half-life in future evaluations.

Automated summary

In this paper, the authors determined the half-life of 68Ga using ionisation chambers measurements and HPGe gamma-ray spectrometry. They reviewed the current literature and identified possible causes of inconsistency within the dataset. The findings suggest that addressing these issues could lead to a significant improvement in future evaluations of the half-life.
