EN 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.
