N2 - Gamow-Teller (GT) strength has been extracted from cross sections for the reaction Fe54(n,p) 54Mn at 0°, 2.5°, 5°, 8°, and 12°, and for an incident energy of 298 MeV. This determination of the + GT strength S+ allows for the first time a full test of the Ikeda sum rule. These data also show that the best available shell-model calculations overestimate this strength by a factor of 2. This result is significant in models of supernovae since electron capture in (fp)-shell nuclei, which is proportional to S+, depletes the relativistic electron gas in precollapse stars.
