| dc.description | Five 14C-labelled organic acids are obtained from the self-radiolysis of high specific activity Ca14CO3. The yields of all products decrease upon isothermal annealing at 548 K. Upon isochronal annealing (1 h), no significant changes occur up to 423 K. In the temperature interval between 476 and 673 K, the yields of formic, oxalic and glyoxylic acids decrease similarly, suggesting that they have the same precursor: the CO- 2 radical. The isochronal annealing behaviours of the precursors of glycolic and acetic acids are more complex and involve other solid state species. © 1991. | |
