我们观察到了激光冷却镱原子在自旋禁戒1 S 0 - 3 P1相互作用谱线上的高分辨光缔合谱。在0 u+状态的振转能级测量的光缔合激光的红色失谐范围从2.9 MHz到1.97 GHz的原子共振。的解离极限附近的振动能级的旋转分裂被完全解决，由于与以前的测量使用自旋允许的单重态跃迁的光谱的亚MHz线宽。此外，从174 Yb和176 Yb的光谱之间的比较，强烈建议的d波形状的共振174 Yb。
We observed high-resolution photoassociation spectra of laser-cooled ytterbium (Yb) atoms in the spin-forbidden 1S0 - 3P1 intercombination line. The rovibrational levels in the 0u+ state were measured for red detunings of the photoassociation laser ranging from 2.9 MHz to 1.97 GHz with respect to the atomic resonance. The rotational splitting of the vibrational levels near the dissociation limit were fully resolved due to the sub-MHz linewidth of the spectra in contrast to previous measurements using the spin-allowed singlet transition. In addition, from a comparison between the spectra of 174Yb and those of 176Yb, a d-wave shape resonance for 174Yb is strongly suggested.
