摘要	Abstract In this paper, we discuss the possibility of using non 0–0 atomic lines as the reference transitions to obtain a magnetically insensitive precision spectra and/or a new atomic clock. The proposed transition operates in a high C-field regime and offers an interesting alternative to the conventional design based on 0–0 transition as the former can effectively eliminate the influence of the first-order Zeeman effect. Using the Breit–Rabi formula, we theoretically calculate the magnetically insensitive frequency and the corresponding C-field value for different alkali atom species. We also provide an estimate of the uncertainty of frequency shift due to the change of C-field. As an example, we demonstrate that high C-field transitions based on Cs : 3 , ? 1 ? 4 , 0 , 3 , 0 ? 4 , ? 1 , and 3 , ? 1 ? 4 , ? 1 , can achieve a bias of 10?14 with a C-field of 10?6 uncertainty. The first-order Zeeman effect free C-field for 3 , ? 1 ? 4 , 0 or 3 , 0 ? 4 , ? 1 transition is roughly one half of that for the 3 , ? 1 ? 4 , ? 1 transition.
