Étude de la réaction du méthane avec l’iode 125 formé par capture électronique du xénon 125

Szilard-Chalmers Reaction of the Trioxalatochromium Ion Adsorbed on an Anion-Exchange Resin under Continuous Elution Conditions

“…8, which shows that these plots can be e.g., an anionie species as well. This fact coincides with the experimental Observation that the anionie ion, [0(0204)2 (H20)2]~ adsorbed on an anion exchange resin was eluted by nitric acid of pu 2 but not at pu 3 [5]. (2) The initial yields at pji 3 and 4 for the various eluents were found to be almost equal (about 0.76), except the case of ps 4 by acetic acid (0.65).…”

“…(3) The somewhat higher values of Kjfi for pn 4 imply that, if the mobility is assumed to be almost unchanged, the recombination rate increases with increasing ps, as was observed already in batch experiments [5]. approximated by straight lines except the case of Ph 2.…”

“…A more rigorous treatment is now being undertaken and will be reported [3]. If the initial quantity of the separable species produced per unit volume of the resin during the Irradiation time At is AXg*, and the quantity of separable species in a time T after its production is AX*, and the recombination reaction obeys the first order rate law, as usually observed [4,5], the quantity of the separable species decreases with time in the resin phase as follows:…”

Reaction of Fission-Recoil Bromine with Methane

“…One half of the yield eould be attributed to a hot-displacement process: I* -t-CH4 ^ CH,I -f H-. ScHEOTH [5] found similar results with iodine activated by thei25Xe (E.C. )I25I process.…”

Chemical Effects of the 76,77Kr-> 76,77Br Decay in Fluoromethanes

“…In the case of I"^, formed through decay of '^^Xe and '^'Xe, it was proved that at least the ('£>2)!''" ion was involved in the reactions with CH4 [39,40]. FROST [14,15]andCOENEN [16,17] discussed the possible role of electronically excited Br"^ ions in the reactions with CH4 and CgHsF, but they did not arrive at defmite conclusions about the relative reactivities of these ions and it could not be proved if reactions of such excited ions are of importance.…”
