MEASUREMENT OF [sup.82,83,84]Kr[sup.82]Sr CROSS SECTIONS IN KURCHATOV INSTITUTE U-150 CYCLOTRON

The activation method was used to determine the cross sections of the nuclear reactions [sup.82]Kr([sup.3]He, 3n)[sup.82]Sr, [sup.83]Kr([sup.3]He, 4n)[sup.82]Sr, and [sup.84]Kr([sup.3]He, 5n)[sup.82]Sr in the [sup.3]He energy range 20-75 MeV on targets with highly enriched krypton isotopes. The results were used to calculate the [sup.82]Sr yield in a yield-optimized cascade target with [sup.82,83,84]Kr and initial [sup.3]He energy 75 MeV. The computed [sup.82]Sr yield was equal to 2.9 MBqf([micro]A x h), which makes it possible to count on the practical application of the method of [sup.82]Sr production based on the reactions [sup.82,83,84]Kr([sup.3]He, xn)[sup.82]Sr in a cascade target.
