Abstract
We have carried out a search for double Gamow-Teller excitations, empl oying the Mg-24(O-18,Ne-18)Ne-24 reaction at 100 and 76 MeV/nucleon at NSCL-MSU and GANIL, respectively, The cross sections for low-lying ex citations are typically a few nb/sr, providing evidence for a strong s uppression of double Gamow-Teller excitations in heavy-ion double char ge exchange, compared to pion-induced reactions. This result does not give good hope that heavy ions at intermediate energies could be used to probe double Gamow-Teller strength.
