摘要(Abstract)：

研究了RbCs(13Π)高位振动态与Ar间的振动能量转移.脉冲激光分别激发自旋禁戒跃迁l3Π(υ=52,53,54←)l1+,利用激光感应荧光(LIF)探测13Π(υ)的弛豫过程,由振动态的有效寿命通过Stern-Volmer公式得到(v=52,53,54)的弛豫速率系数分别是(3.7±0.4),(4.0±0.4)和(4.4±0.4)×1012cm3m-1,速率系数随v的增加而增大.激光只激发v=54态,改变检测激光与泵浦激光间的延迟时间,分别测量(v=54,53,52)态的LIF相对强度随时间的演化.从三粒子速率方程组,由积分布居数得到v=54→53和v=54→52转移速率系数分别为(1.9±0.4),(0.28±0.06)×1012cm3m-1,单量子弛豫Δv=1占总弛豫速率系数的43多量子弛豫Δv>1在高位振动态弛豫过程中是重要的.
