我们报道了利用镱原子的光学费什巴赫共振效应来控制散射波函数。窄互组合线((1)S(0)-(3)P(1))用于Ciurylo等人提出的有效控制。修订A 71, 030701(R)(2005)]。利用另一个激光引起的光缔合速率的变化来监测散射波函数的变化。光学费什巴赫共振对（172）Yb等具有较大负散射长度的同位素特别有效，并且我们已经证实，散射相移除以波数，即给出零能量极限下的散射长度，大约改变了30 nm。
We report control of the scattering wave function by an optical Feshbach resonance effect using ytterbium atoms. The narrow intercombination line ((1)S(0)-(3)P(1)) is used for efficient control as proposed by Ciurylo et al. [Phys. Rev. A 71, 030701(R) (2005)]. The manipulation of the scattering wave function is monitored with the change of a photoassociation rate caused by another laser. The optical Feshbach resonance is especially efficient for isotopes with large negative scattering lengths such as (172)Yb, and we have confirmed that the scattering phase shift divided by the wave number, which gives the scattering length in the zero energy limit, is changed by about 30 nm.
