Abstract
Cross sections for the (), the (), and the () reactions for , , , and , and the () reaction for have been measured from threshold to 40 MeV at the Iowa State University Synchrotron Laboratory. Cross section results were obtained by unfolding bremsstrahlung yield curves. A "total" photoabsorption cross section was obtained for each isotope by adding the partial cross sections together. Cross sections integrated to 40 MeV are given for each reaction. Giant resonance parameters obtained from the total cross sections are compared with the results of a dynamic collective model calculation. Cross section strength is found at energies above the giant dipole resonance and is discussed in terms of the integrated cross sections.
