Comment on "Resonant and nonresonant contributions to the photoactivation of 111Cd"

摘要: The most recent investigation of the photoactivation isomeric nuclei reported by Kr{hacek c}mar {ital et} al}. continues to contain a strong contribution from nonresonant channels. In this Comment we report that integrated cross sections for resonant levels in {sup 87}Sr, 111}Cd, and 113,115}In have been calculated nuclear structure data compared those experimental results which assert contributions are important. latter shown systematically smaller values amount missing strength can be correlated magnitude section found these investigations. Monte Carlo simulations realistic geometries display important components photon fields, resulting environmental Compton scattering, omitted previous analyses data. shape as function experimentally parameters suggest explained entirely on basis excitation mechanism without any need introduce contribution.
