Abstract

At three-photon barium and strontium atom ionization the intermediate two-photon resonances with the triplet states were discovered. The ion yield maxima corresponding to two-photon singlet-singlet and singlet-triplet resonances have approximately the same amplitude. Large probability of two-photon excitation of the triplet states sharply differed from the case for one-photon excitation. The possible reasons leading to large probabilities of two-photon excitation of the triplet states are discussed.
