双脉冲原子相干控制（2PACC）光谱的Eley-Rideal反应。原子Laser的一个应用
Two-Pulse Atomic Coherent Control (2PACC) Spectroscopy of Eley-Rideal Reactions. An Application of an Atom Laser
摘要：
提出了原子激光的光谱应用。被称为2PACC的光谱学利用来自双脉冲原子激光的物质波的相干性质。这些波用于控制气体表面化学复合反应。该方法被证明为氢或碱原子激光脉冲的Eley-Rideal反应，其中表面目标是吸附的氢原子。反应产生氢或碱金属氢化物分子。解吸附的气相分子产率和它的内部状态被证明是由两个原子激光脉冲之间的时间和相位延迟控制。计算是基于非绝热框架下求解含时薛定谔方程。作为预测的2PACC信号的解吸概率已经被计算为脉冲参数的函数。
英文摘要：
A spectroscopic application of the atom laser is suggested. The spectroscopy termed 2PACC employs the coherent properties of matter-waves from a two pulse atom laser. These waves are employed to control a gas-surface chemical recombination reaction. The method is demonstrated for an Eley-Rideal reaction of a hydrogen or alkali atom-laser pulse where the surface target is an adsorbed hydrogen atom. The reaction yields either a hydrogen or alkali hydride molecule. The desorbed gas phase molecular yield and its internal state is shown to be controlled by the time and phase delay between two atom-laser pulses. The calculation is based on solving the time-dependent Schrodinger equation in a diabatic framework. The probability of desorption which is the predicted 2PACC signal has been calculated as a function of the pulse parameters.
