In this article radiative parameters for atomic chromium were determined by a semi-empirical method. The eigenvector amplitudes, determined in our previously published work concerning the hyperfine structure parametrization for even-parity atomic chromium levels, were used. The calculated values of oscillator strengths and lifetimes for low-lying metastable Cr I levels are presented. On the basis of the calculations performed, a possible clock transition in neutral chromium is proposed. Possible detection schemes for the clock transition were investigated experimentally and are presented in this work.

原子铬中提出的时钟跃迁和可能的检测方案

在本文中，原子铬的辐射参数是通过半经验方法确定的。使用了在我们之前发表的关于偶校验原子铬水平的超精细结构参数化的工作中确定的特征向量幅度。给出了低位亚稳态 Cr I 水平的振荡器强度和寿命的计算值。基于所执行的计算，提出了中性铬中可能的时钟转换。对时钟转换的可能检测方案进行了实验研究，并在这项工作中提出。
