Measurement of the Tm 169 (n, 3n) Tm 167 cross section and the associated branching ratios in the decay of Tm 167


Journal Article

© 2016 American Physical Society. The cross section for the Tm169(n,3n)Tm167 reaction was measured from 17 to 22 MeV using quasimonoenergetic neutrons produced by the H2(d,n)He3 reaction. This energy range was studied to resolve the discrepancy between previous (n,3n) cross-section measurements. In addition, the absolute γ-ray branching ratios following the electron-capture decay of Tm167 were measured. These results provide more reliable nuclear data for an important diagnostic that is used at the National Ignition Facility to estimate the yield of reaction-in-flight neutrons produced via the inertial-confinement-fusion plasma in deuterium-tritium capsules.
