Abstract
We report the observation of the predicted metastable 4p(3) S-4 state in th e Ca- ion utilizing a spectroscopic technique based on nonlinear resonant m ulticolor absorption via an autodetaching state. The binding energy of the S-4 state is determined to be 586.86(10) meV with respect to the parent Ca( 4p(2) P-3) state, a value less than 3 meV from the predicted one. The lifet ime of the SS state is determined to be larger than 7 ps.
