A pulse-radiolysis technique has been used to estimate G(eaq-) at elevated temperatures up to 250°C. Observation in pure water indicated that absorbance at λmax of eaq- increases significantly with temperature, by 1.4 times in going from 20 to 250°C, when compared at supposedly equivalent times by which most of spur decay probably finishes at each temperature. This temperature dependence was considered to arise primarily from variation in G(eaq-) itself. In another series of experiments Cd2+ was used as an eaq- scavenger. The estimated G(Cd+) in a dilute Cd2+ solution was 3.5 and 3.8 respectively at 200 and 250°C in accord with the above estimation on the temperature dependence of G(eaq-).
