Abstract

We have measured the photoproton cross sections of ${}^{88}{Sr}$ and ${}^{90}{Zr}$ for production of ground and low-energy residual states. The results are in agreement with predictions of the particle-hole model for isobaric analog states. Strong and broad resonances are found around 21 MeV in ${}^{88}{Sr}$ and around 20 and 22 MeV in ${}^{90}{Zr}$ which agree with coherent states expected by the theory.
