摘要：

Advances towards the realization of an absolute frequency standard in the submillimetre region are reported. The **3P//1 B ARR LR **3P//0, DELTA m//j equals 0 fine-structure transition in the metastable triplet of **2**4Mg has been observed in an atomic beam with a Ramsey-type interrogation technique. Its frequency, measured with an accuracy of plus or minus 3 multiplied by 10** minus **1**1 with respect to a Cs standard, turned out to be v//0 equals (601,277,157,860 plus or minus 20) Hz.
