Identification of new isomers in Ac : Impact on dark matter searches
K. W. Kim, G. Adhikari, E. Barbosa de Souza +50
We report the identification of metastable isomeric states of Ac at 6.28 keV, 6.67 keV and 20.19 keV, with lifetimes of an order of 100 ns. These states are produced by the…

Comparison between DAMA/LIBRA and COSINE-100 in the light of Quenching Factors
Y. J. Ko, K. W. Kim, G. Adhikari +46
There is a long standing debate about whether or not the annual modulation signal reported by the DAMA/LIBRA collaboration is induced by Weakly Interacting Massive Particles~(WIMP)…

Search for a Dark Matter-Induced Annual Modulation Signal in NaI(Tl) with the COSINE-100 Experiment
100 Collaboration, G. Adhikari, P. Adhikari +46
We present new constraints on the dark matter-induced annual modulation signal using 1.7 years, of COSINE-100 data with a total exposure of 97.7 kgyears. The COSINE-100 expe…
