The ETNA software has been developed to compute efficiency transfer and coincidence summing corrections. Different experiments are combined to test the validity of this last facility. Point sources with multi-gamma emitters are measured at several source-to-detector distances. Experimental correction factors are determined from the variation in the peaks' relative intensities versus the geometrical conditions. The ETNA code is used to compute the corrections due to coincidence summing for the same geometries. The calculated values are compared to the experimental ones.
