Charge-exchange spectra for the /sup 90/Zr(p,n) reaction at 200 MeV are calculated over the range -70< or =Q/sub pn/ (MeV)< or =0, in an effort to assess the degree of quenching and/or redistribution of Gamow-Teller strength. Comparison with the data suggests that the mixing of 1p-1h with 2p-2h states provides the most plausible explanation of the missing Gamow-Teller strength. Predicted spectra for anticipated (n,p) data are also presented and it is indicated how such data may provide additional insight into the issue of missing Gamow-Teller strength.
