研究了高强度脉冲光学晶格中超声速冷却分子的快速减速产生静止冷分子的方法。以重分子I{sub 2}为例，我们预测了在减速期间系方程组速度分布函数的演化，并表明在亚微秒时间尺度上，可以在数百微米的长度尺度上产生温度低于1k、密度约为10{sup 12} cm{sup -3}的静止冷分子。
We study the creation of stationary cold molecules by rapid deceleration of supersonically cooled molecules in a high-intensity pulsed optical lattice. Using the heavy molecule I{sub 2} as an example we predict the evolution of the velocity distribution function of the ensemble during the deceleration period, and show that stationary cold molecules with temperatures below 1 K and densities of approximately 10{sup 12} cm{sup -3} can be produced over length scales of hundreds of micrometers on submicrosecond time scales.
