摘要

The cross-sections of the 97Mo(α,x)95,97Ru and 97Mo(α,x)96gTc reactions were measured by the stacked foil technique within the energy range 58.5 → 19.4 MeV on cyclotron U-150. Cross-section of 97Ru reaches 650 mb at ~ 50 MeV. Data for energies above 46 MeV were obtained for the first time. The experimental data are in a good agreement with the simulation with TALYS software. The TTY (thick target yield) of 97Ru at 58.5 MeV is ~ 12 MBq/(μA∙h), which is enough for practical application. The presence of radioisotopic impurities of ⁹5Ru is not a critical concern due to its short half-life.
