论文摘要
d $ _2 $的电离能是通过涉及两次多普尔多普勒多普勒的真空脉冲激光激发和近红外连续波激光激发以产生$ e_ \ e_ \ mathrm {i}（i}（i}（\ mathrm {d} d} _ 264 = 124）， \ wn。从这个值中，D $ _2 $的解离能量为$ d_0 $（d $ _2 $）= 36 \，748.362 \，282（26）\ wn \ wn，比以前的值提高了25倍，与以前的价值相比，在良好的一致性（$1.6σ$）的量子和量子中，量子不合时宜的4级量化和量化4级的量化量，并具有4级的量化。更正为$mα^6 $。该结果构成了分子结构域中量子电动力学的测试，而打开透视图来确定分子的核电荷半径。
The ionization energy of D$_2$ has been determined experimentally from measurements involving two-photon Doppler-free vacuum-ultraviolet pulsed laser excitation and near-infrared continuous-wave laser excitation to yield $E_\mathrm{I}(\mathrm{D}_2)=124\,745.393\,739(26)$ \wn. From this value, the dissociation energy of D$_2$ is deduced to be $D_0$(D$_2$) = 36\,748.362\,282(26) \wn, representing a 25-fold improvement over previous values, and found in good agreement (at $1.6σ$) with recent ab initio calculations of the 4-particle nonadiabatic relativistic energy and of quantum-electrodynamic corrections up to order $mα^6$. This result constitutes a test of quantum electrodynamics in the molecular domain, while a perspective is opened to determine nuclear charge radii from molecules.
