Abstract: | The level structure of90Mo is investigated via the beta decay of90g Tc and90m Tc whose half-lives are measured to be 8.7±0.2 and 49.2±0.4 s, respectively. The decay properties are studied by means of beta and gamma spectroscopy techniques. The level structure of90Mo populated in the decays of both isomers is proposed with deducedJ π values. Theβ-decay energies for90g Tc and90m Tc are 8.8±0.3 and 9.3±0.3 MeV, respectively. The structure is discussed in terms of the shell model. |
