The decay scheme of 54Mn is judged to be complete since these are the only two levels populated in 54Cr below the decay energy. The β– decay branch is negligible and has not been included in this evaluation. The spin, parity and half-life of the 54Cr excited level were adopted from the evaluation by 2006Hu08. 2.

Decay Scheme 108 Ag m disintegrates 90.9 (6) % by electron capture to the 1 771 keV excited state in Pd-108, and by 9.1 (6) % through isomeric transitions (two gamma-rays in cascade) in Ag-108. Ag 108m has been found to decay 8.5% of the time via a two-step isomeric cascade consisting of a 30.4-keV M4 transition followed by a 79.4-keV E1 transition. The remaining 91.5% of the decays proceed by an electron-capture transition to a 1770-keV level in Pd 108. Abstract This study focuses on two radioisotopes of silver, (108m)Ag and (110m)Ag, characterized by a complex decay scheme.

Ag-108m decay scheme

The α-decay is shown as follows: + + + The α-decay energies are 5.486 MeV for 85% of the time (the one which is widely accepted for standard α-decay energy), 5.443 MeV for 13% of the time, and 5.388 MeV for the remaining 2%. The γ-ray energy is 59.5409 keV for the most part, with little amounts of other energies following it.

Spin and parity 2 - were ascribed to the 80 keV level of Ag 108 on the basis of the multipolarity of the 79.5 keV transition. In the decay scheme of Ag 108m the sequence of the levels 4 + (1047 keV) and 0 + (1049 keV) is given and the existence of the levels 1454 keV and 1469 keV is confirmed.

For total uncertainty add 2.4% systematic component in quadrature, based on the normalization factor 5.03E-3(12). This study focuses on two radioisotopes of silver, (108m)Ag and (110m)Ag, characterized by a complex decay scheme. Each isotope has two disintegration modes, the isomeric transition leading to the daughter isotope ((108)Ag and (110)Ag, respectively) with a short half-life.
