The 2.5 Minute of Ba Daughter of Cs(137),

Abstract

An isomeric state of stable Ba(137) which decays by gamma emission to the ground state with a half-life of 2.5 minutes has been discovered. This metastable state is formed by beta-decay of Cs(137). The Ba(137) gamma has an energy of 0.75 Mev and is 13% internally converted giving rise to approx 0.7 Mev conversion electrons and K x-rays.
