Observation of low-lying isomeric states in ${}^{136}$Cs: a new avenue for dark matter and solar neutrino detection in xenon detectors

We report on new measurements establishing the existence of low-lying isomeric states in ${}^{136}$Cs using $\gamma$ rays produced in ${}^{136}$Xe(p,n)${}^{136}$Cs reactions. Two states with…
