Abstract
This paper describes the setup of a high-temperature cell for water pulse r adiolysis and the preliminary result of e(aq)(-) observation. The experimen t was performed using D2O at 25-400 degreesC including supercritical al con ditions. The e(aq)(-) formation in supercritical water was confirmed. Tempe rature dependences of e(aq)(-) spectrum and G epsilon (max) were investigat ed. With increasing temperature, it was found that absorption peak shifts s ignificantly to lower energy (red shifting) and G epsilon (max) decreases. (C) 2001 Elsevier Science Ltd. All rights reserved.
