Observation of ^186mTa

Unreported tantalum isomer ^186mTa has been produced through the reaction ^186W（n,p） by irradiation of aatw with 14 MeV neutrons. The activity of ^186mTa and ^186Fa was measured using HPGe detectors and several X-γ as well as γ-γ coincidence arrangements. The ^186mTa has been identified by means of...

Zusammenfassung:	Unreported tantalum isomer ^186mTa has been produced through the reaction ^186W（n,p） by irradiation of aatw with 14 MeV neutrons. The activity of ^186mTa and ^186Fa was measured using HPGe detectors and several X-γ as well as γ-γ coincidence arrangements. The ^186mTa has been identified by means of measuring known γ rays from ^186Ta β-decay. The half-life of ^186mTa has been determined to be （1.5±0.1） min.
