Cross-sections of Neutron Threshold Reactions Studied by Activation Method

Popis výsledku v původním jazyce

The neutron cross-sections of various threshold reactions using different quasi-monoenergetic neutron sources based on proton reaction on 7Li target were studied. The measurements were carried out in NPI ASCR in Řež near Prague and in TSL in Uppsala (Sweden) and neutron sources with energy range from 20 to 100 MeV were used. The last experiment was carried out in February 2010 in TSL Uppsala using proton beams with energies of 65, 70, 80, and 93 MeV. Cross-sections of (n,xn), (n,p) and (n,alpha) reactions in Au, Al, Ta, Bi, Y, In foils and iodine samples were determined. Activated foils and iodine samples were measured by the means of HPGe detectors and a wide range of spectroscopic corrections was applied. Our preliminary values of experimental cross-sections are compared with the results of TALYS code and also with data from EXFOR database. Many cross-sections were measured in the energy regions where no experimental data are available so far.
