Intensities of the γ-ray emissions following the 111Sn decay determined via photonuclear reaction yield measurements

Intensities of ten strongest γ -ray transitions following 111 Sn ( T 1 / 2 = 35 . 3 m) decay have been determined via comparison of two sets of the experimental photonucleon reaction yields driven using traditional activation equation and activation equation for genetically coupled nuclei of the 111 Sn → 111 In → 111 Cd radioactive chain. The found absolute intensities of the γ -ray transitions in question turned up to be noticeably different from the currently recommended values.
