title: [The study of resonant multi-photon ionization mechanism in the vapour of sodium].
abstract: By two-photon resonant three-photon ionization and two-photon hybrid resonant three-photon ionization in Na2-Na the different ion current strength with different temperature was measured. The result was discussed.
