Study on the Charge Transfer in Matters Induced by the Intense Electric Field of the Picosecond Coherent Radiation

利用电子直线加速器的高能电子束产生的相干辐射，建立了皮秒半周期光源系统。研究了光的电场诱导的极性分子的运动和取向。首次观察到光照强度对水、金属氧化物纳米粒子和植物高分子材料透射谱的影响。建立了利用皮秒脉冲电子和脉冲光组成的脉冲辐解系统，并将其应用于水分子行为的瞬变现象研究。

A picosecond half-cycle light source system was established by using the coherent radiation generated from high-energy electron bunch of an electron linear accelerator. The motion and the orientation of polar molecules induced by the electric field of the light was investigated. The effect of the light intensity on the transmission spectra for water, metal oxide nanoparticles and high molecular materials of plants was first observed. The pulse radiolysis system using the picoseconds pulsed electrons and the pulsed light was established and was applied to the study of the transient phenomena on the behavior of water molecules.
