用正交场方法在脉冲超声束中制备了主量子数为圆里德伯态的氦原子。从这种状态到thecircular状态的过渡，在频率接近38.5 GHz的高分辨率微波光谱，进行测量静态磁场和电场沿着传播的光束与量子状态选择检测脉冲电场电离轴。通过射频光谱测量1.3和1.6 mT之间的磁场，相对精度为，通过微波光谱测量±1.3µT，绝对校准，考虑到多普勒频移和弱杂散电场的影响，达到±2.0µT，空间分辨率为mm。在1.74 mm（35 mm）的基线上，磁场梯度可被确定为±1.49µT/mm（nT/mm）的精度。为了进行这些测量，静态电场和动态斯塔克效应的贡献被最小化，并且在装置中的三个空间维度中的每一个中的残余电场被测量到±750µV/cm之间的绝对精度。在这项工作中使用的方法可以转移到其他原子或分子的实验中。因此，它们非常适合应用于微创，绝对静态场磁力测量和静电测量，例如，在里德伯原子和超导电路之间的混合界面;在束缚态QED或弱等效原理与原子或分子氢，反氢或正电子素的测试中;以及通过回旋辐射发射光谱测量绝对中微子质量。
Helium atoms in pulsed supersonic beams have been prepared in the circular Rydberg state with principal quantum numberusing the crossed-fields method. High-resolution microwave spectroscopy of the transition from this state to thecircular state, at frequencies close to 38.5 GHz, was performed to measure static magnetic and electric fields along the axis of propagation of the beams with quantum-state-selective detection by pulsed-electric-field ionization. Magnetic fields of between 1.3 and 1.6 mT were measured to a relative precision ofby rf spectroscopy and ±1.3µT by microwave spectroscopy, with absolute calibration, accounting for Doppler shifts and effects of weak stray electric fields to ±2.0µT and a spatial resolution ofmm. Magnetic-field gradients could be determined to a precision of ±1.49µT/mm (nT/mm) over a baseline of 1.74 mm (35 mm). To perform these measurements, static electric fields and contributions from the motional Stark effect were minimized, and residual electric fields in each of the three spatial dimensions in the apparatus were measured to an absolute precision of betweenand ±750µV/cm. The methods used in this work can be transferred to experiments with other atoms or molecules. They are therefore well suited for applications in minimally invasive, absolute static-field magnetometry and electrometry, for example, at hybrid interfaces between Rydberg atoms and superconducting circuits; in tests of bound-state QED or the weak equivalence principle with atomic or molecular hydrogen, antihydrogen, or positronium; and in measurements of the absolute neutrino mass by cyclotron radiation emission spectroscopy.
