The Q-value and decay properties of114Ag

Abstract

The decay of mass separated a14Ag has been studied with /?-and y-ray spectroscopy. The total /?-decay energy has been accurately determined to (5.16___0.11)MeV using a /?7-coincidence technique. A detailed decay scheme has been constructed.

“…Branching ratios of all the transitions decaying from this level and measured in the present experiment agree well with the previous values, except for the 1842-keV transition to the ground state. Our value disagrees with the thermal neutron capture data [12] but agrees with the 114 Ag β-decay data [38]. The disagreement with the thermal neutron capture data could be because the 1842-keV transition is a doublet and that might not have been understood in the thermal neutron capture measurement.…”

“…In nuclear resonance fluorescence, strong dipole excitation has been observed for states at 2800, 3000, and 3110 keV in 114 Cd [29]. The parities of the states at 3000 and 3110 keV could not be resolved in the present or previous measurements; however, from the vanishing yield of these states in the β decay of 114 Ag [38], we tentatively assign negative parity to these states. We confirm the 1 + spin and parity assignment for the 2800-keV state.…”

Achieving a complete resolution of the ambiguity of the 0 + states is difficult, and it has been suggested that these states might have lost their own characteristic behavior through strong mixing of their normal and intruder properties [32].…”
