Dataset for: A new low uncertainty measurement of the 111Ag half-life

################################################################################################## This repository contains Microsoft Excel spreadsheet and gamma-spectrometry data for the paper: A new low uncertainty measurement of the 111Ag half-lifeGiancarlo D'Agostino, Matthieu Guyon, Andrea Gandini, Giorgio Grosso, and Marco Di Luzio DOI: Giancarlo D'Agostino et al 2026 Appl. Radiat. Isot. (https://doi.org/10.1016/j.apradiso.2026.112786) ################################################################################################## Open the "Elab_111Ag_data_half life.xls" Microsoft Excel spreadsheet for data processing to obtain the half-life of 111Ag. There are 5 sheets named "111Ag 342.1 keV OR20", "Elab (OR20)", "111Ag 342.1 keV OR50", "Elab (OR50)", "Elab (OR20 & OR50)", "Uncertainty" for data elaboration and plot, and 1 sheet named "Import data" for data import. The contents of the cells are highlighted in their headers and, in some cases, in their comments. The spreadsheet is self-explained. The workflow is import the data in "Import data", then copy and paste the cells "Name, Start day, Start hour", "Real time [sec], Live time [sec]", and "E [keV], Area [cnt], Area unc [cnt]" to "111Ag 342.1 keV OR20" and "111Ag 342.1 keV OR50" sheets. Data are elaborated in sheets "Elab (OR20)" and "Elab (OR50)" to obtain separated 111Ag values and in sheet "Elab (OR20 & OR50)" to obtain a single 111Ag value. Results, including the correlation matrix, are achieved iteratively by coping and pasting the fitting results (111Ag half-life value and pulses pile-up constant value) in "111Ag 342.1 keV OR20" and "111Ag 342.1 keV OR50" sheets. The uncertainty budget is produced in "Uncertainty" sheet. The effects due to pulses pile-up, stability, decay correction and gamma-peak fitting are evaluated by adjusting values affecting the "biasing factor" cells in "111Ag 342.1 keV OR20" and "111Ag 342.1 keV OR50" sheets. Gamma-spectra collected with the OR20 and OR50 detection systems running the Ortec Gamma Vision software are available in the "Gamma_Spectra" folder together with the calibration gamma-spectra and peak list files obtained with the HyperLab software. Peak list files include the information to be imported in the Microsoft Excel spreadsheet. Contact: For any request or need, please contact `[e-mail]`.
