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…
Development of an array of HPGe detectors with 980% relative efficiency
D. S. Leonard, I. S. Hahn, W. G. Kang +7
Searches for new physics push experiments to look for increasingly rare interactions. As a result, detectors require increasing sensitivity and specificity, and materials must be s…
Lowering the energy threshold in COSINE-100 dark matter searches
G. Adhikari, E. Barbosa de Souza, N. Carlin +43
COSINE-100 is a dark matter detection experiment that uses NaI(Tl) crystal detectors operating at the Yangyang underground laboratory in Korea since September 2016. Its main goal i…
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)…
First Results from the AMoRE-Pilot neutrinoless double beta decay experiment
V. Alenkov, H. W. Bae, J. Beyer +104
The Advanced Molybdenum-based Rare process Experiment (AMoRE) aims to search for neutrinoless double beta decay (0) of Mo with 100 kg of Mo-enriched moly…
