Influence of the interaction volume on the kinetic energy resolution of a velocity map imaging spectrometer

“…For instance, the resonant ionization shows some peaks which are very close to each other in the photoelectron KE spectra. [23][24][25][26] Moreover, Stark splitting [27][28][29] induces some fine structures in the KE spectra of photoelectrons. To distinguish such subtle structures, many new designs are proposed to improve the resolution of VMI spectrometers in recent years.…”
