The linewidth of the excitation spectrum for multiphoton ionization is found to be broadened much more severely than the cascade fluorescence originating from the resonant intermediate level. These results are due to the mutual effects of the ionizing and resonating transitions, which are not properly accounted for in perturbative treatments.

This paper presents the results of an experimental study of the process of multiphoton ionization of alkaline earth atoms in the presence of intermediate forbidden quadrupole energy resonances using different schemes of optical transitions to obtain new spectroscopic information on the probabilities of forbidden quadrupole energy transitions.
