Nitric acid, pulse radiolysis

In marked contrast there exists a volumnous literature on pulse radiolysis studies of nitric acid solutions (9). The NO3 radical has been identified as a major product although the mechanism of formation is still a matter of debate. While a number of reactions of this radical have been reported (10) there has evidently not been any pulse radiolysis studies of reactions with Pu ions.

Post-irradiation reduction of cerium (IV) in concentrated sodium nitrate solutions was previously reported by Pikaev, Glazunov, and Yakubovich (20) in pulsed electron irradiations of 0.8IV sulfuric acid containing 0.5M sodium nitrate and 2 X 10"4M cerium (IV). They attributed the post-irradiation reaction to intermediate formation of pernitric acid, originally suggested by Allen (1) as an intermediate in the radiolysis of nitric acid solutions. Furthermore, they ruled out nitrous acid since it has been shown previously that the non-radiolytic reaction between cerium (IV) and nitrous acid goes to completion very quickly under the same conditions. However, they presented no evidence to refute the... 

A value of in the range 1-2.5 x 10 is suggested. Pulse radiolysis of nitric acid involves attack by the hydroxyl radical to yield NOj as the main...
