Conference paper


The (p,n) reaction has been successful in delineating the Gamow-Teller strength function in the nuclear excitation spectrum; however, the total strength extracted from experiment is less than that expected from the sum rule if only nucleon spin and isospin degrees of freedom are important in nuclei. Apparently the missing strength is shifted to higher excitation energies primarily through mixing with both 2p-2h and A-h configurations; however, an experimental test is needed to decide the relative importance of these two principal mechanisms.
