Abstract :
Absolute differential and integrated-over-angle cross sections for the reactions 12C(γ,π0)12C and 13C(γ,π0)13C leaving the residual nuclei in the ground state have been measured with tagged bremsstrahlung photons in the near threshold region (170.1 MeV ≤ Eγ ≤ 176.8 MeV). This reaction mechanism is sensitive to the whole nuclear volume and the coherent processes which occur are revealed by comparing the extracted cross sections for both isotopes with each other and with theoretical calculations.
