摘要：

Spur decay kinetics of the hydrated electron following picosecond pulse radiolysis of water have been measured using a time-correlated transient absorption technique with an asynchronous mode-locked laser. The 11 us time window afforded by this signal-averaging technique is ideal to match up with more: conventional transient absorption measurements taken to microsecond time scales. The precise data recorded in this study require a revision downward of the "time zero" solvated electron yield to approximately 4.0 per 100 eV of energy absorbed, to match the best available scavenger product measurements.
