Gamow-Teller strength functions in the resonance region are calculated in the full ([ital pf])[sup 8] space. The observed profile is very sensitive to the level density and may become so diluted as to be confused with background. A model independent proof is given that standard quenching originates in nuclear correlations, and that some 30% of the total strength must be due to states outside the ([ital pf])[sup 8] space. By combining this argument with the results of shell model calculations, comparison with the [sup 48]Ca([ital p],[ital n])[sup 48]Sc experimental data strongly suggest that most of the strength that is currently thought to be missing is actually observed.
