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 …

Possible evidence of nonstatistical properties in the $^{35}$Cl(n,p)$^{35}$ cross section

The $^{35}$Cl(n,p) and $^{35}$Cl(n,α) cross sections at incident neutron energies between 2.42 - 2.74 MeV, were measured using the Berkeley High Flux Neutron Generator. The cross sections for $^{35}$Cl(n,p) were more than a factor of three to five …

Design, construction, and characterization of a compact DD neutron generator designed for $^{40}$Ar/$^{39}$Ar geochronology

A next-generation, high-flux DD neutron generator has been designed, commissioned, and characterized, and is now operational in a new facility at the University of California Berkeley. The generator, originally designed for $^{40}$Ar/$^{39}$Ar dating …
