Measurement of 134Xe(n,2n)133m,gXe reaction cross sections in the 14-MeV region with detailed uncertainty quantification
Listed in ScienceDB
A lead-shielded HPGe detector and offline g–ray spectra of the residual product were used to measure the cross-section (CS) and ratios of isomeric CS (sm/sg) in 134Xe(n,2n)133m,gXe reactions at different energies (13.5 MeV, 13.8 MeV, 14.1 MeV, 14.4 MeV, 14.8 MeV) relative to the 93Nb(n,2n)92mNb reaction CS.
Description
The target was high-purity natural Xe gas under high pressure. The T(d,n)4He reaction produces neutrons.
TALYS code (version 1.95) for nuclear reactions was used for calculations, with default parameters and nuclear level density models. The uncertainties in the measured CS data were thoroughly analyzed using the covariance analysis method. The results were compared with theoretical values, evaluation data, and previous experimental findings.

CS data of the 134Xe(n,2n)133mXe and 134Xe(n,2n)133gXe reactions and the corresponding isomeric CS ratios at 13.5 MeV, 13.8 MeV, and 14.1 MeV neutron energies are reported for the first time. This research advances our knowledge of pre-equilibrium emission in the (n,2n) reaction channel by resolving inconsistencies in the Xe data.
