论文摘要
我们通过结合光碎片的分子光解离和吸收成像来证明在高磁场处的NARB Feshbach分子的检测。光解离过程是通过光谱选择的超细Zeeman级别进行的，与Na（$ 3P_ {3/2} $） + RB（$ 5S_ {1/2} $）异常相关，在自发性排放和光学泵送之后，它导致了与单一级别的单个校准性，该渐变是在自发性排放和光学泵送之后。在解离之后，通过检测结果$^{23} $ na和$^{87} $ rb原子来获得分子数。我们还研究了由光解离过程引起的加热效果，并优化了提取分子云温度的检测方案。该方法使$ in的$ intu $检测NARB Feshbach分子之间的快速时间尺度碰撞动力学，并且将是研究涉及分子的几种物理学的宝贵能力。
We demonstrate detection of NaRb Feshbach molecules at high magnetic field by combining molecular photodissociation and absorption imaging of the photofragments. The photodissociation process is carried out via a spectroscopically selected hyperfine Zeeman level correlated with the Na ($3P_{3/2}$) + Rb ($5S_{1/2}$) asymptote which, following spontaneous emission and optical pumping, leads to ground-state atoms in a single level with near unity probability. Subsequent to the dissociation, the number of molecules is obtained by detecting the resultant $^{23}$Na and $^{87}$Rb atoms. We have also studied the heating effect caused by the photodissociation process and optimized the detection protocol for extracting the temperature of the molecular cloud. This method enables the $in~situ$ detection of fast time scale collision dynamics between NaRb Feshbach molecules and will be a valuable capability in studying few-body physics involving molecules.
