Název v původním jazyce

The spectrum-averaged cross section investigation of 117Sn(n,n’)117mSn and 67Zn(n,p)67Cu reactions

Popis výsledku v původním jazyce

The spectrum averaged cross sections (SACS) in standard neutron field, e.g. Cf-252(s.f.), is a preferable tool for cross section evaluation and validation. A set of reaction measurements with high energy thresholds was previously performed. The presented work focuses on lower energy threshold reactions, namely on the inelastic scattering of the tin foil, more specifically the reaction Sn-117(n,n')Sn-117m, and the zinc foil reaction, namely Zn-67(n,p)Cu-67. These reactions are of special interest due to their intermediate energy range, which is essential in classical reactor dosimetry and fast reactor dosimetry. The experiments were carried out in a standard neutron field formed by Cf-252(s.f.) source in Rez. The experimental results were compared with calculations using MCNP6.2, ENDF/B-VII.1 transport library, and ENDF/B-VIII.0 and IRDFF-II cross section data library. Additionally, the calculations using CEA code DARWIN/PEPIN2 using JEFF-3.0/A were executed. The obtained experimental SACS of previously measured reactions were in good agreement with the SACS calculated using the IRDFF-II library. Additionally, the calculational reaction rate of Zn-67(n,p)Cu-67 was in accordance with the experimental data in case of ENDF/B-VIII.0 nuclear data library. Moreover, the calculational results of Sn-117(n, n')Sn-117m obtained by DARWIN/PEPIN2 code (using JEFF-3.0/A nuclear data library) are closest to the experimental results.
