Cross-section measurements of the 156Dy(n, 2n)155Dy reaction at neutron energies higher than 17 MeV

In the present work the cross section of the 156Dy (n, 2n) 155Dy reaction (Eth = 9.51 MeV) was measured at neutron beam energies above 17 MeV: 17.1, 18.1, and 19.0 MeV. The irradiations were performed at the 5.5-MV tandem accelerator of the Institute of Nuclear and Particle Physics at N.C.S.R. Demokritos, where quasimonoenergetic neutron beams were produced via the 3H (d, n) 4He reaction. The cross-section measurements were performed by means of the activation technique relative to the 27Al (n, alpha) 24Na reference reaction. Within the present work the experimental study is framed by theoretical calculations performed via the TALYS code (version 1.95).

Automated summary

In this study, the cross section of the 156Dy (n, 2n) 155Dy reaction was measured at neutron beam energies above 17 MeV, specifically at 17.1, 18.1, and 19.0 MeV. The experimental measurements were complemented by theoretical calculations performed using the TALYS code version 1.95.
