高精度干涉测量方法数据集

针对考核指标4.1的“高精度干涉测量方法”，发展了低温离子阱-高分辨离子速度成像谱仪装置，实现分子解离碎片的振转态分辨的单量子态和全角度空间分布探测，以及好于 0.02eV分辨的平动能性质测量，选取Ar-N2+、CO2+的经窄线宽激光局域激发的解离动力学，通过对解离产物振转态分辨和全角度空间分布探测，表明研究激发态空间构象和电荷转移对不同解离产物量子态的调控.

Targeting the "high-precision interferometry method" specified in assessment indicator 4.1, we developed a cryogenic ion trap-high-resolution ion velocity imaging spectrometer setup. This apparatus enables the detection of single quantum states and full angular spatial distributions of molecular dissociation fragments with rovibrational state resolution, alongside measurements of translational kinetic energy properties with a resolution better than 0.02 eV. We selected the dissociation dynamics of Ar-N2+ and CO2+ locally excited by narrow-linewidth lasers as research subjects. Through detecting the rovibrational state-resolved and full angular spatial distributions of the dissociation products, we demonstrated that excited-state spatial conformation and charge transfer regulate the quantum states of different dissociation products.
