| Abstract: | Using the sputtered a+oms of a short pulse and high repetition rate uranium hollow cathode lamp as vapour source, a CW dye lasar as exciting light, and detecting with fluorescence method, we have measured the time constant of decay in the ground state and the lifetime in the metastable state of U atoms in HCD lamp. |

| Keywords: | Uranium decay rate metastable state lifetime |
