摘要: Two-dimensional photoelectron spectroscopy of hydrogen iodide (HI) has been performed in the photon energy region 11.10-14.85 eV, order to investigate dynamical properties on autoionization and neutral dissociation Rydberg states HI*(RA) converging HI+(A 2Sigma1/2(+)). A two-dimensional spectrum exhibits strong vibrational excitation HI+(X 2Pi) over a from approximately 12 13.7 which is attributable autoionizing feature 5 dpi state. noticeable set stripes 13.5-14.5 eV assigned as resulting atomic I* I+ (3P0 or 3P1). The formation understood terms predissociation multiple by way repulsive potential curves HI+(4Pi1/2).
