Abstract
We report the detection of a series of elements via 2 + 1 (photons to resonance + photons to ionize) resonance ionization mass spectrometry. The efficiency of this process is demonstrated, as the two-photon step can often be saturated. Examples are given where experimental observations of ion yields are compared to theoretical calculations based on a simple formalism used for two-photon transition rates, coupled with a rateequations calculation of the total ionization rate. Advantages of 2 + 1 ionization compared with more widely used 1 + 1 processes are discussed.
