The¹⁰⁷Ag(n, γ)¹⁰⁸Ag reaction

Abstract

The 107Ag(n, gamma )108Ag reaction has been studied using a variety of techniques: (i) thermal neutron capture-primary gamma rays measured with a pencil-shaped Ge(Li) detector; 45-1200 keV gamma rays measured with a bent-crystal spectrometer; 10-80 keV gamma rays measured with a Si(Li) detector; conversion electrons measured with a magnetic spectrometer; gamma-gamma coincidences studied with Ge(Li) detectors; (ii) resonance neutron capture-low-energy gamma rays following both single-resonance (16 eV) and average-resonance (2 and 24 keV) neutron capture have been analysed. The data obtained from these measurements have enabled the construction of a level scheme of 108Ag containing 65 excited states with precisely determined energies. Spin and parity assignments have been made for most of the levels. The neutron binding energy in 108Ag has been determined as 7269.6+or-0.6 keV.
