Time-resolved study of the A(2)Pi state of CaH by laser spectroscopy

• A time-resolved experiment on the A(2)Pi state of gaseous calcium hydride has been performed by applying laser spectroscopic methods. The following zero-pressure lifetime was obtained for the CaH A(2)Pi state: tau(nu=0) = 33.2 (+/- 3.2) ns and tau(nu=1) = 33.7 (+/- 5.2) ns. The lifetime was found to be the same for the A(2)Pi(1/2) and Delta(2)Pi(3/2) states.
