Abstract
The EC/beta(+)-decay of the odd-odd nucleus Ag-100 was studied by mean s of total absorption gamma-ray spectrometry. Most of the Gamow-Teller strength was found to be concentrated at an excitation energy of 5.6 MeV in Pd-100, the FWHM of this resonance being 1.5 MeV. The measured strength distribution which is interpreted within the BCS approximatio n as being due to the dominant population of four-quasiparticle excita tions, resembles the distribution predicted by an advanced shell-model calculation for the Ag-98 --> Cd-98 decay.
