Abstract

The National Institute of Standards and Technology (NIST) performed new standardization measurements for ⁶⁴Cu. As part of this work the photon emission probability for the main gamma-ray line and the half-life were determined using several high-purity germanium (HPGe) detectors. Half-life determinations were also carried out with a NaI(Tl) well counter and two pressurized ionization chambers.

Keywords: (64)Cu; Gamma-ray spectrometry; Half-life; Photon emission probability; Pressurized ionization chambers.
