Influence of enriched ¹⁰⁰Mo on Mo reaction yields

Abstract

In accelerator-driven 99 Mo/ 99m Tc production, the 100 Mo enrichment level should be chosen carefully as it greatly affects the yields of the involved Mo reactions. To facilitate selecting the 100 Mo enrichment level, we defined a figure of merit called density change coefficient and developed its calculation program. Density change coefficients calculated for nine commercial enriched 100 Mo products are presented and their use in selecting the 100 Mo enrichment level is discussed. Theory Molybdenum hierarchyWe classify Mo into three hierarchical groups as described in figure 3: (i) Mo materials, (ii) Mo element, and (iii) Mo isotopes. The Mo materials of interest in this paper were Mo metal and Mo(VI) oxide (MoO 3 ), both of which
