摘要(Abstract)：

利用泵浦-检测技术和光学吸收技术,对K(6S)与H2反应生成的初生态产物KH(X1Σ+,v=0,1)的转动态分布和反应截面作了测量。脉冲激光双光子激发K原子至K(6S)态,通过泵浦-探测技术确定了KH(X1Σ+,v=0,1)初生态的转动分布,转动分布接近样品池温时的统计分布。通过测量泵浦激光的能量损失确定K(6S)态原子密度,测量检测激光的吸收系数得到反应产物KH分子的密度,由速率方程分析可以得到转动分辨的反应截面,总的反应截面为所有转动分辨的反应截面之和,得到的反应截面分别为(1.3±0.5)×10-16cm2(对v=0)和(0.05±0.02)×10-16cm2(对v=1).
