Search for solar axions by Primakoff effect with the full dataset of the CDEX-1B Experiment

We present the first limit on g₀ coupling constant using the Bragg-Primakoff conversion based on an exposure of 1107. 5 kg days of data from the CDEX-1B experiment at the China Jinping Underground Laboratory. The data are consistent with the null signal hypothesis, and no excess signals are observed. Limits of the coupling g₀5. 3~eV/c² at 95\% C. L.
