Gamow-Teller strength in the continuum

Abstract

We present the results of a decomposition of the angular distribution of the continuum observed in the ${}_{}{}^{90}{}_{}{}^{}\mathrm{Zr}(p, n)$ reaction at 200 MeV into different angular momentum transfers. We found significant amounts of $L=0\mathrm{}$ strength over a wide range of excitation energies in the continuum, which sums up to more than half of the missing Gamow-Teller strength.
