First search for light fermionic dark matter absorption on electrons using germanium detector in CDEX-10 experiment
J. X. Liu, L. T. Yang, Q. Yue +83
We present the first results of the search for sub-MeV fermionic dark matter absorbed by electron targets of germanium using the 205.4~kgday data collected by the CDEX-10 ex…

Constraints on inelastic dark matter from the CDEX-1B experiment
Y. F. Liang, L. T. Yang, Q. Yue +83
We present limits on spin-independent inelastic weakly interacting massive particles (WIMP)-nucleus scattering using the 737.1 kgday dataset from the CDEX-1B experiment. Exp…

Evaluation of cosmogenic Ge-68 background in a high purity germanium detector via a time series fitting method
W. H. Dai, J. K. Chen, H. Ma +4
Ge-68 is a cosmogenic isotope in germanium with a half-life of 270.9 days.Ge-68 and its decay daughter Ga-68 contribute considerable background with energy up to 3 MeV to low backg…
