Application of the sum peak method to determine the perturbed angular correlation parameters in biological specimens

Application of the sum peak method to determine the perturbed angular correlation parameters in biological specimens

The counting rate of a sum peak formed by two γ-ray emissions in radioactive decay of a nuclide depends on its integral attenuation factor Ḡ 22. Therefore, in the “sum peak method”, the Ḡ 22 value for the specimen in question can be obtained merely from sum peak measurements using one radiation dete...

Zusammenfassung:The counting rate of a sum peak formed by two γ-ray emissions in radioactive decay of a nuclide depends on its integral attenuation factor Ḡ 22. Therefore, in the “sum peak method”, the Ḡ 22 value for the specimen in question can be obtained merely from sum peak measurements using one radiation detector when the resolution time and the geometry are fixed. The procedure to determine the Ḡ 22 values is described for specimens containing 111In, together with the detailed relationships between the sum peak counting rates and the values of Ḡ 22.
