From: Accurate Electron Affinity of Iron and Fine Structures of Negative Iron ions
Photoelectron image and spectrum of Fe− at photodetachment energies 13414.38 cm−1.
The double arrow indicates the laser polarization. Peak d is a result of photodetachment from Fe−(4F9/2) to Fe(3F4), which is used to determine the electron affinity of Fe. The vertical red spikes are the theoretical simulations at the ion temperature 800 K.
