Abstract

The molecular-frame photoelectron angular distribution (MFPAD) of the satellite accompanying the C 1s photoline of the CO2 molecule has been measured at the C 1s(2σg)→ 4σ*u shape resonance, using electron-ion multicoincidence momentum spectroscopy. The observed MFPAD indicates that the conjugate satellite is excited by internal inelastic scattering. In this scenario, a photoelectron is ejected from the C 1s(2σg) orbital along the molecular axis and collides with an O lone-pair electron in the highest occupied molecular orbital 1πg. Then one of the colliding electrons is trapped to the lowest unoccupied molecular orbital 2π*u, while the other is emitted as a satellite photoelectron of σg symmetry, losing the information of the original photoelectron emission direction and parity.
