Summary
By the coincidence studies of113Sn and by studying113Sn sources completely separated from113In, the existence of a level at 650 keV in113In resulting, in the emission of 258 keV γ-ray has been established. This state is fed by the electron capture transition in113Sn to the extent of about 3.5%. The decay energy of113Sn leading to the 650 keV state has been calculated to be 36 keV. In the decay of121Tem and121Te γ-rays of energy 70 keV and 1130 keV have been observed.
Riassunto
Con lo studio delle coincidenze del113Sn e studiando sorgenti di113Sn completamente liberate da113In è stato identificato nel113In un livello a 650 keV risultante nell’emissione di raggi γ di 258 keV. Tale stato è alimentato per circa il 3.5% dalla transizione per cattura d’elettrone nel113Sn. L’energia di decadimento del113Sn che porta allo stato di 650 keV è stata calcolata in 36 keV. Nel decadimento del121Tem e del121Te sono stati osservati raggi γ di 70 keV e 1130 keV d’energia.
