A magnetic bottle time of flight spectrometer has been used to perform spectroscopy of K n+ and Rb n+ states with ionization degrees n of 2, 3 and 4. Energy levels are directly measured by detecting in coincidence the n electrons that are emitted as a result of single photon absorption. Experimental results are compared with the energies from the NIST atomic database [1] and ab initio multiconfiguration Dirac-Fock calculations. Previously unidentified 3p 4 ( 3 P)3d 1 4 D energy levels of K 2+ are assigned.
Multielectron coincidence spectroscopy has been used to study the Auger decay following the core (4f)—valence (5d, 6s) double photoionization of atomic mercury. Multiconfiguration Dirac–Fock calculations have been performed to predict the transition energies and populations of the triple ionized Auger final states. A good agreement between the experiment and simulated spectra is found.
