Cross-section Measurements of (n,xn) Threshold Reactions in Au, Bi, I, In, and Ta

Popis výsledku v původním jazyce

We measured neutron cross-sections of various threshold reactions using different quasi-monoenergetic sources in the range 17 - 94 MeV. Our motivation comes from the "Energy plus Transmutation project", in which Al, Au, Bi, In, Ta, Co, Y foils are used to measure the flux of high energy neutrons produced in spallation reactions. Unfortunately, no experimental cross-section data for observed threshold (n,xn) reactions are available at neutron energies above 20 MeV. We performed 11 measurements of the (n,xn) cross-sections using the neutron source in NPI ASCR cyclotron in Řež and at TSL cyclotron in Uppsala (EFNUDAT program). Quasi-monoenergetic neutrons from p+Li reaction irradiated above mentioned foils. Irradiated foils were measured on HPGe detectorsand spectroscopic corrections were applied to obtained cross-section data. A comparison with TALYS cross-section calculations was performed.
