Cross-sections for formation of ~(195m)pt through ~(nat)Pt(n,x)~(195m)Pt reaction over neutron energy range 13-15 MeV

摘要

The cross-sections for formation of metastable state of ~(195)Pt (~(195m)Pt, 98.85 keV, 4.02 d) through ~(nat)Pt(n,x)~(195m)Pt reaction induced by 13.5-14.6 MeV neutrons were measured. Measurements were corrected for gamma-ray attenuations, random coincidence (pile-up), dead time and fluctuation of neutron flux. The data for ~(nat)Pt(n,x)~(195m)Pt reaction cross-sections are reported to be 438 ± 46, 399 + 44 and 372 + 43 mb at 13.5 + 0.2, 14.1 ± 0.1 and 14.6 + 0.2 MeV incident neutron energies, respectively.
