Chemistry of Positronium. Part V: Inhibition of Positronium Formation by Oxalic Acid and Oxalates in Aqueous Solutions

摘要

The inhibiting powers towards positronium formation of H sub 2 C sub 2 O sub 4 , HC sub 2 O sub 4- , C sub 2 O sub 4-- and mixtures of these solutes in aqueous solutions have been measured. Whereas complete inhibition can be observed in solutions of the first two solutes, C sub 2 O sub 4-- yields only a limited decrease in the intensity of positronium. These results are discussed in terms of the spur model and of hot positron or positronium . (Atomindex citation 09:416794)
