Multiphoton spectroscopy of doubly excited autoionizing states of Ca
Abstract
The autoionizing spectrum of Ca has been studied in the wavelength ranges of 490-540 nm and 555-590 nm through multiphoton absorption and the subsequent decay to excited Ca+(4p 2P32.1/2/) states. The fluorescence signal of Ca+(4p) exhibits resonances attributed to the 3d6p and 3dnf (n=4-7) doubly excited autoionizing J=1, 3 states (three-photon absorption) together with resonances due to excited bound states (two-photon absorption) of the …
