The decays of ^109,111Pd and ¹¹¹Ag following neutron capture by Pd

Improved precisions of the energies and intensities of the γ rays emitted in the decays of ¹⁰⁹Pd and ^111g,mPd have been obtained based on a high-resolution spectroscopic study of these γ emissions from radioactive samples produced by neutron capture by natural Pd. Correspondingly improved values of the energies and β feedings of the levels in the ^109,111Ag daughters have been deduced. More precise energies and intensities have also been determined for the γ rays emitted in the decays of the ¹¹¹Pd daughter activities ^111g,mAg to ¹¹¹Cd. - Highlights: • High-resolution γ-ray spectrometry in radioactive decays of ¹⁰⁹Pd, ^111g,mPd, and ^111g,mAg. • Order-of-magnitude improvement in precision of γ-ray energies and intensities. • 36 γ-rays previously unobserved in radioactive decay studies reported. • 12 unknown and 10 roughly estimated weak β intensities replaced with precise values.
