Summary form only given. Excess photon detachment (EPD) occurs when an electron is released from a negative ion with an energy corresponding to the absorption of more photons than the minimum number needed for detachment. We study the EPD of the simplest two-electron atom the negative hydrogen ion, with photons of energy 1.17 eV. Our time of flight (TOF) spectrum can be interpreted as an EPD spectrum with photoelectron peaks corresponding to single- and two-photon absorption.
