Measurement of 82,83,84Kr(3He, xn)82Sr Cross Sections in Kurchatov Institute U-150 Cyclotron

Abstract

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