我们首次在超冷原子蒸气中观测到非偶极跃迁。我们在磁光阱中激发了23 Na中的3 P-4P电四极（E2）跃迁，并通过首次测量4P（1/2）能级的超精细结构和提取磁偶极常数A=30.6+/-0.1 MHz，展示了它在高分辨率光谱学中的应用。我们使用连续光-光双共振伴随光电离来探测跃迁。
We report the first observation of a nondipole transition in an ultracold atomic vapor. We excite the 3P-4P electric quadrupole (E2) transition in 23Na confined in a magneto-optical trap, and we demonstrate its application to high-resolution spectroscopy by making the first measurement of the hyperfine structure of the 4P(1/2) level and extracting the magnetic dipole constant A=30.6+/-0.1 MHz. We use cw optical-optical double resonance accompanied by photoionization to probe the transition.
