The instrument resolution was the order of one percent and the energy measurements should be reliable. A decay scheme was proposed strictly on the basis of matching gamma-ray energies and is found to disagree seriously with that presented here.
The decay equation for the beta decay is either 55 137 → ∗+ +𝜈̅ −1 𝑒 0 56 137 followed by 137 ∗→ 56 56 +𝛾 137 or alternatively 137 055 →13756 +−1 +𝜈̅𝑒 where the barium nucleus is created directly in its ground state. The decay scheme of the 𝛾-decay: h 11/2- 661,659 keV

In This Experiment, You Will Be Studying The Decay Of Metastable Barium-137 To Determine If It Is In Fact First 137 decays to a short-lived decay product, barium-137m. The latter isotope emits gamma radiation of moderate energy, which further decays to a stable form of barium. The time required for a radioactive substance to lose 50 percent of its radioactivity by decay is known as the half-life. Cesium-137 is significant because of 2016-04-01 137m, the metastable state that is a product of Cs -137 radioactive decay. The half-life is the amount of time it takes N radioactive nuclei to decay to half of the original radioactive nuclei. The isotope generators that we are using contain up to 10 μCi (370 kBq) of Cs-137 (± 20%) bound on a special ion exchange medium and can produce the [8] BNM-CEA/DTA/DAMRI Nuclear and Atomic Decay Data ; 19/12/98 .

half-life of an isotope of barium, Ba-137m, a metastable state of barium before it decays to its ground state. The activity of the Ba-137m is measured as a function of time by detecting the gamma rays that are emitted and the half-life is computed from the decay rate constant. Answer and Explanation: Gamma-rays (0 0γ 0 0 γ) have no charge and no mass.

The longest-lived isomer is 133m Ba, which has a half-life of 38.9 hours, though the shorter-lived 137m Ba (half-life 2.55 minutes) arises as the decay product of the common fission product caesium-137. Barium-114 is predicted to undergo cluster decay, emitting a nucleus of stable 12 C to produce 102 Sn.
This particular isotope of caesium is both a beta and gamma emitter. It is produced in some abundance by fission reactions.

Beta decay changes $Z$ which may produce a hole in the K shell ("shake-up"). That hole then decays. But that is then the K-shell of the progeny nucleus: barium.
