“…Clearly, the PES contains three sharp peaks which result from photoionization of the resonantly excited level 5p and of two lower-lying levels, 3d and 4p, which are populated by spontaneous decay out of 5p. The relative peak heights are determined by the spontaneous decay rates which can be found in the NIST atomic database [19] as well as by different photoionization cross sections of the individual levels [20,21]. Photoionization of the 5s level is suppressed by a Cooper minimum in the photoionization cross section near the used photon energy [20].…”

We present a simple diode laser-based photoionization scheme for generating electrons and ions with well-defined spatial and energetic (≲2 eV) structures. This scheme can easily be implemented in ion or electron imaging spectrometers for the purpose of off-line characterization and calibration. The low laser power ∼1 mW needed from a passively stabilized diode laser and the low flux of potassium atoms in an effusive beam make our scheme a versatile source of ions and electrons for applications in research and education.
