Abstract

A minimum in the partial photoionisation cross section for the ²Π_u state of C₂H₂ at hv ≈ 14 eV is accompanied by a significant departure of the vibrational intensities from the Franck-Condon distribution. Using an explicit formula for resonant photoemission we show with model calculations that a resonance ≈3 eV above the first ionisation potential is responsible for this effect.
