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…

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…
