Abstract

A new method to normalize coincidence counts for γ-γ angular correlations measured with a multiple-Ge detector system is described. This method uses characteristic KX-rays emitted following internal conversion or electron capture, which exhibit a coincidence with γ-rays and an isotropic KX-γ angular correlation. Only the ratios between KX-ray counts and γ-ray counts of interest in the same gated spectra are used to deduce normalized coincidence intensities, and any other quantities such as detector efficiencies, γ-ray singles counts and other kinds of efficiencies are not required. Performance of this method was tested in on-line experiments using mass-separated ¹²⁶La and ¹²⁸La sources.
