This article compiles an extensive dataset on L subshell Coster-Kronig (C-K) and Auger decays (AD). This paper's primary objective is to aggregate 1058 experimental values from literature covering the years 1955 to 2024, taken from 130 scholarly articles and presenting them in seven tables. The reported values are systematically organized and provided with their associated errors in two to four-digit format. Additionally, the tables include computed weighted average values, uncertainty values, combined standard deviations, and average z-scores. The dataset refers to elements from 28Ni to 100Fm, investigated under photon bombardment. The compiled experimental data distribution includes most elements. Nevertheless, there were some isolated cases where either no data or fewer than two data points were present.
