Description
A high-precision half-life measurement for the radioactive isotope, 26Na, was performed at TRIUMF’s Isotope Separator and Accelerator (ISAC) facility. This is the first experimental test of the high-efficiency Gamma-Ray Infrastructure for Fundamental Investigations of Nuclei (GRIFFIN) spectrometer for performing high precision (± 0.05% or better) half-life measurements [1]. In this talk, I will discuss new results of the half-life obtained from gating on 1809-keV γ-ray photopeaks that include corrections for pile-up and deadtime losses. The results obtained from these techniques will be compared to a previous high-precision measurement of the that employed direct β counting [2].
KEYWORDS: radioactive isotope, half-life, deadtime, pile-up
