Boutique neutrons advance (40)Ar/(39)Ar geochronology
We designed and tested a compact deuteron-deuteron fusion neutron generator for application to (40)Ar/(39)Ar geochronology. The nearly monoenergetic neutrons produced for sample irradiation are anticipated to provide several advantages compared with conventional fission spectrum neutrons: Reduction...

description | We designed and tested a compact deuteron-deuteron fusion neutron generator for application to (40)Ar/(39)Ar geochronology. The nearly monoenergetic neutrons produced for sample irradiation are anticipated to provide several advantages compared with conventional fission spectrum neutrons: Reduction of collateral nuclear reactions increases age accuracy and precision. Irradiation parameters within the neutron generator are more controllable compared with fission reactors. Confidence in the prediction of recoil energies is improved, and their likely reduction potentially broadens applicability of the dating method to fine-grained materials without vacuum encapsulation. Resolution of variation in the (39)K(n,p)(39)Ar neutron capture cross section at 1.3 to 3.2 MeV and discovery of a strong resonance at ~2.4 MeV illuminate future pathways to improve the technique for (40)Ar/(39)Ar dating. |
