Abstract

A generalized uncertainty calculation formalism has been applied to the ratio and product of γ-ray detector efficiencies at different energies. The correlation decreases the uncertainty of the efficiency ratio for close energy values but increases the uncertainty for their product. Applications of the results are presented for comparator experiments applicable in PGAA and partial γ-ray cross section calculations, and for the uncertainties of true coincidence corrections.
