Abstract

Microscopic analyses of complete forward angle intermediate energy (p,n)-spectra are presented for the reactions 90Zr(p,n), 208Pb(p,n) and 42Ca(p,n). It is shown that the whole spectra up to an excitation energy of Ex = 70 MeV are the result of correlated one-particle-one-hole (1p1h) spin-isospin transitions only. The spectra reflect, therefore, the linear spin-isospin response of the target nucleus to the probing (p,n) field. We find a large amount of the “missing” Gamow-Teller strength in the continuum part of the O0 spectrum. Then the total amount of Gamow-Teller strength observed in these nuclei is close to the lower sum rule limit of 3(N-Z).
