The interaction potential characterizing the ground electronic state of MgAr+ has been determined from the photoelectron spectrum recorded from the a 3Π0 metastable state of MgAr at high resolution by pulsed-field-ionization zero-kinetic-energy (PFI-ZEKE) photoelectron spectroscopy. The photoelectron spectrum provides information on the first ten vibrational levels of MgAr+ and leads to the determination of the adiabatic ionization energy of metastable MgAr (38 742.3(20) cm-1), the ground state dissociation energy of MgAr+ (1254(60) cm-1), and to the characterization of the rovibrational photoionization dynamics of MgAr.
