Measurement of 49V half-life
The accepted value for the 49V half-life is either 330±15 days, based on a few old measurements with large dispersion, or 338±5 days, from a more recent measurement. Methods of study have included proportional counting and NaI X-ray detection. A new direct measurement of the 49V half-life has been c...

| Zusammenfassung: | The accepted value for the
49V half-life is either 330±15 days, based on a few old measurements with large dispersion, or 338±5 days, from a more recent measurement. Methods of study have included proportional counting and NaI X-ray detection. A new direct measurement of the
49V half-life has been carried out for over 2.5 half lives using liquid scintillation counting, as an additional contribution due to the scarce measurements of this radionuclide. A half-life value of 328.6±3.3 days was determined on the basis of an overall uncertainty analysis of 0.99%. |
