ACTIVATION TECHNIQUE OF ASTROPHYSICAL PHOTONUCLEAR REACTION RATE MEASUREMENTS USING BREMSSTRAHLUNG

Astrophysical simulation of natural abundance of p-nuclei needs knowledge of the enormous quality of photonuclear reaction rates which can be derived from the reaction integral yields. The applicability of the activation technique for getting relevant experimental information is shown by the examples of the (gamma, n)-reactions running in the Ru-96 and Ru-98 p-nuclei the measurements of the integral yields of which have been performed using bremsstrahlung of the Kharkiv electron linear accelerator. The obtained data are compared to the statistical theory of nuclear reactions.
