The {sup 97}Ag{yields}{sup 97}Pd{beta}-decay was investigated by using a total absorption spectrometer and an array of 6 Euroball-Cluster Ge detectors. A total of 603 {gamma}-rays de-exciting 151 levels in {sup 97}Pd have been assigned. The Gamow-Teller {beta}-decay strength distributions from the experiment and a shell-model calculation are compared, revealing a dominant resonance around a {sup 97}Pd excitation energy of 4 MeV with a width of about 1.5 MeV. An experimental quenching factor of about 4.9(7) for the total Gamow-Teller strength was obtained, which is close to the predicted theoretical hindrance factor.
