The magnitudes of correction are 4%-17% for the standard 152 Eu source measured in this study. The relative deviation of 4.7% before the coincidence correction is reduced to 0.8% after the correction is applied to the efficiency based on the measured gamma line. Naturally occurring europium (63 Eu) is composed of 2 isotopes, 151 Eu and 153 Eu, with 153 Eu being the most abundant (52.2% natural abundance).While 153 Eu is observationally stable, 151 Eu was found in 2007 to be unstable and undergo alpha decay. 121.7817 3 : 28.58 6 : e+b + : 125.69 13 : 0.016 5 : e+b + : 148.010 17 : 0.037 4 : e+b + : 173.17 15 : 0.008 3 : b- : 175.18 : 0.0040 11 : e+b + : 192.60 4 : 0.00679 72 This is a table of commonly-observed gamma energies, arranged by increasing gamma energy.

This importance is even more critical when dealing with nanostructured materials, where the surface-to-volume ratio is considerably higher and the surface term accounts for a much larger fraction of the total free energy.
