Development of Portable Spectrometer Based on CZT Detector Under Nuclear Anti-Terrorism

Journal of Isotopes, 2021
Nuclear terrorism has the characteristics of strong concealment, great harm, wide range and complex composition. Once it happens, it will cause serious casualties, property losses and social panic.

Probing the N = 32 shell closure below the magic proton number Z = 20: Mass measurements of the exotic isotopes 52,53K [PDF]

, 2015
The recently confirmed neutron-shell closure at N = 32 has been investigated for the first time below the magic proton number Z = 20 with mass measurements of the exotic isotopes 52,53K, the latter being the shortest-lived nuclide investigated at the ...

The puzzle of the synthesis of the rare nuclide 138La [PDF]

, 2001
The calculations of the p-process in the O/Ne layers of Type II supernovae are quite successful in reproducung the solar system content of p-nuclides. They predict, however, a significant underproduction of the rare odd-odd nuclide 138La. A model for the

Widespread erosion on high plateaus during recent glaciations in Scandinavia [PDF]

, 2018
Glaciers create some of Earth’s steepest topography; yet, many areas that were repeatedly overridden by ice sheets in the last few million years include extensive plateaus.

Discordance between cosmogenic nuclide concentrations in amalgamated sands and individual fluvial pebbles in an arid zone catchment [PDF]

, 2014
Based on cosmogenic 10Be and 26Al analyses in 15 individual detrital quartz pebbles (16–21 mm) and cosmogenic 10Be in amalgamated medium sand (0.25–0.50 mm), all collected from the outlet of the upper Gaub River catchment in Namibia, quartz pebbles yield
