Yankwich, Peter E.(2010). Loss of Radioactivity from Barium Carbonate Samples. Lawrence Berkeley National Laboratory. Lawrence Berkeley National Laboratory: Lawrence Berkeley National Laboratory. Retrieved from: http://www.escholarship.org/uc/item/62c6h58k
The exchange loss of radioactivity from solid samplos of barium carbonate through the agency of carbonic acid and its ions has been investigated under a variety of conditions. It is concluded that the losses observed are greatly dependent upon the me

Intermolecular 13C kinetic isotope effects in the decomposition in dioxane solution of oxalic acid to carbon dioxide and formic acid were determined at several temperatures between 80 and 132 °C. The isotope effect is normal in sign (k12C ≳ k13C),
