Abstract
Half-lives ought to be accurate, and preferably precise as well. This contribution discusses cases of long-lived radionuclides used in measurements with accelerator mass spectrometry (AMS), where multiple half-life measurements on specific radionuclides do not agree within the stated uncertainties. This we call “unsettled” half-lives. We include also some cases where only very old half-life measurements (>50 years ago) exist, sometimes only one single measurement. Half-life measurements of the following radionuclides are being discussed: ³²Si, ⁵³Mn, ⁵⁹Ni, ⁷⁹Se, ¹³⁵Cs, ¹⁴⁶Sm, and ²⁰⁹Po. These radionuclides are of interest for a variety of applications with AMS where accurate half-life values would be important.
