Dynamics of State-Selected and Ultra Cold Collisions (Physics)

选态非弹性碰撞动力学研究 将继续使用碱原子。 在新的补助期内， 主要项目将进行：（1）能源转移交叉 截面作为速度和极化的函数， 反应物原子;（2）锂原子的缔合电离 碰撞作为速度和极化的函数;（3） 超低温碰撞中的缔合电离 使用单个原子束和声光调制多普勒 谱 这些研究将探索原子的本质 在新的速度区域中的新的细节相互作用，并将 允许与理论进行比较， 参数范围。

A study of inelastic collision dynamics in state-selected alkali atoms will be continued. In the new grant period three major projects will be undertaken: (1) energy transfer cross sections as a function of velocity and polarization of the reactant atom; (2) Associative ionization in lithium atom collisions as a function of velocity and polarization; (3) Associative ionization in collisions at ultra-cold temperatures using a single atomic beam and acousto-optic modulated Doppler spectroscopy. These studies will explore the nature of atomic interactions in new detail in new regions of velocity, and will allow comparison with theory over a correspondingly broader range of parameters.
