摘要：

The J = 0 <-- 1 and J = 1 <-- 2 fine-structure transitions in atomic Fe in its ground D-5 State have been detected in the laboratory by far-infrared laser magnetic resonance. The fine-structure intervals have been measured accurately as 2696.3942(22) and 5519.9397(18) GHz, respectively; these values correspond to wavelengths of 111.18273 and 54.31082 mu m, with an uncertainty of about 2 x 10(-5) mu m.
