The half-life of 126Sn refined by thermal ionization mass …

The results obtained on 3 loads of 2 μg Sn are listed in Table 3 and shown in Fig. 1. Two different modes have been used to correct the 126 Sn/ 118 Sn ratios for isobaric contribution. The data on the left-hand side of Table 3 are corrected for CaPO 3 + contributions only, whereas those on the right-hand side include a superimposed correction for tellurium, assuming natural …

Thermal ionization

In thermal ionization, also referred to as surface ionization, chemically-purified material loaded onto a filament which is then heated to cause some of the material to be ionized as it boils off the hot filament. Filaments are generally flat pieces of metal around 1-2mm wide, 0.1mm thick, bent into an upside-down U shape and welded to steel posts that supply a current.
