建议研究碰撞的作用， 在改变辐射场的相互作用中起作用的过程 原子。 将使用的技术涉及推导 一个传输型方程，它既考虑了原子场， 和碰撞的相互作用。 关于将《公约》 极化效应和变速碰撞效应 将结合起来，以获得一个全面的理论的线型 在四波混频中。 它被提议解释压力引起的 使用能量守恒以统一的方式产生额外的共振 参数，并应用于四波混频，量子拍 和光电离。 将对下列问题进行研究： 辐射场与被困原子的相互作用，包括 瞬态反应、发射的辐射以及 原子与光场相互作用的碰撞过程。

It is proposed to investigate the role which collisional processes play in modifying the interaction of radiation fields with atoms. The techniques to be used involve the derivation of a transport-type equation which accounts for both the atom-field and collisional interactions. Work on the inclusion of polarization effects and velocity-changing collisional effects will be combined to obtain a comprehensive theory of line shapes in four-wave mixing. It is proposed to explain pressure-induced extra resonances in a unified manner using conservation of energy arguments, with applications to four wave mixing, quantum beats and photoionization. Studies will be undertaken of the interaction of radiation fields with trapped atoms, including transient responses, radiation emitted and the role of collisional processes on the atom-field interaction.
