Anton Wallner featured on 2Physics

Anton Wallner, from VERA, Austria as well as Dept of Nuclear Physics, Australian National University, Canberra, Australia (insert appropriate joke about the existence of Kangaroos here) was recently featured on 2Physics with our work on the half-life of 60Fe [1].

It’s always good to see that colleagues get the attention that they deserve, and, as we are working on another project right now, I hope that we can continue our cooperation!

Abstract = {Almost all archaeological ceramics undergo slow, progressive rehydroxylation by chemical combination with environmental water. The reaction is accompanied by an expansion, and also by the small but measurable mass gain that provides the basis of the RHX dating method. The rate of the RHX reaction increases with increasing temperature. Here we describe comprehensively the effects of temperature on the RHX process in relation to the dating methodology. We deal in turn with the kinetic model of the RHX reaction, the temperature dependence of the RHX rate, and the influence of varying environmental temperature on the RHX mass gain. We define an effective lifetime temperature and show how this is calculated from an estimated lifetime temperature history. Historical meteorological temperature data are used to estimate the lifetime temperature history, and this can be adjusted for long-term climate variation. We show also how to allow for the effects of burial in archaeological sites on the temperature history. Finally we describe how the uncertainties in estimates of RHX age depend on the estimates of temperature history and effective lifetime temperature.},
