For $^{124}$Xe this process has not yet been observed and its detection would provide a new reference for nuclear matrix element calculations. We have conducted a search for two-neutrino double electron capture from the K-shell of $^{124}$Xe using 7636 kg$\cdot$d of data from the XENON100 dark matter detector. Using a Bayesian analysis we observed no significant excess above background, leading to a lower 90 % credibility limit on the half-life $T_{1/2}>6.5\times10^{20}$ yr. We also evaluated the sensitivity of the XENON1T experiment, which is currently being commissioned, and find a sensitivity of $T_{1/2}>6.1\times10^{22}$ yr after an exposure of 2 t$\cdot$yr.STAMPAenArticle10.1103/PhysRevC.95.0246052-s2.0-85015641988http://arxiv.org/abs/1609.03354v2https://journals.aps.org/prc/abstract/10.1103/PhysRevC.95.0246052017PhRvC..95b4605AFIS/01 - FISICA SPERIMENTALE
