✦ Synopsis

The state-selective photoelectron imaging technique is applied to investigate the angular distribution of ejected electrons and the electronic state of the atomic ion produced by (2 + 1) resonance-enhanced multiphoton ionization of iodine atom in the photolysis of CH3I. Strong anisotropic distribution behaviors have been depicted on two electron images observed, one • 2 o . , • 4 o ..... via the two-photon resonance D5/z state from ground state ~odme and, another via D~/z from spin-orbit excited ~odlne. ....... 2 o ......

The configuration of core electrons ~s preserved m the ~omzat~on from the Ds/z mtermedmte state, whale the ~omzatlon from the D~/2 state shows two distinct ionization paths, a preserved and a non-preserved path of core electrons.
