| Abstract: | A time-resolved experiment on the A2Π state of gaseous calcium hydride has been performed by applying laser spectroscopic methods. The following zero-pressure lifetime was obtained for the CaH A2Π state: τυ´=0 = 33.2 (±3.2) ns and τυ´=1 = 33.7 (±5.2) ns. The lifetime was found to be the same for the A2Π½ and A2Π3/2 states. |
