Neutron transmission measurements were carried out on the separated isotopes of silver using the time-of-flight facility at the Japan Atomic Energy Research Institute electron linear accelerator. Neutrons were detected with the <SUP>6</SUP>Li-glass detectors at 56 and 191 m. The samples used were metallic powder enriched to 98.2% for <SUP>107</SUP>Ag and 99.3% for <SUP>109</SUP>Ag. Transmission data were analyzed with the multi-level Breit-Wigner formula incorporated in a least squares fitting program. Resonance energies and neutron widths were determined for the large number of resolved resonances in the neutron energy region of 400 eV7 keV. The <I>s</I>-wave strength functions and average level spacings were obtained to be ; <I>S</I><SUB>0</SUB>= (0.43±0.05)×10<SUP>-4</SUP>, <I>D</I><SUB>0</SUB>=20±2 eV for <SUP>107</SUP>Ag and <I>S</I><SUB>0</SUB>= (0.45±0.05)×10<SUP>-4</SUP>, <I>D</I><SUB>0</SUB>= 20±2 eV for <SUP>109</SUP>Ag.
