โœฆ Synopsis

Two-color multiphoton excitation spectra of autoionizing ('Da) ns and nd Rydberg series in atomic iodine are presented in the region of the I+ t D, ionization threshold. The first laser is used to produce atomic iodine by photodissociation of methyl iodide and to pump the iodine atoms to low-lying ('Da) 6p states via a two-photon transition. The second laser excites single photon transitions from these states to autoionizing Rydberg series, resolved to n = 35. Extension of this technique for other open shell atoms is discussed.

It has been found that higher excited states, populated by two-photon absorption, ionize with an effkiency which, in the energy range of 5.3-6.4 eV, is independent of the energy of the excitation. This behavior is similar to that observed in sequential twostep excitation (exciton photoionization) an
