Phys. Rev. Lett. 41, 1463–1467 (1978)Observation of Electric-Field-Induced Resonances above the Ionization Limit in a One-Electron AtomReceived 19 April 1978; published in the issue dated 20 November 1978 Measurements of the relative photoionization cross sections of Rb in the presence of various strengths of external electric fields are reported. Systematic, field-dependent, resonance structure is observed not only for energies above the classical field-ionization limit, but above the zero-field ionization limit as well. A striking dependence of the cross section upon light polarization is also observed. © 1978 The American Physical Society URL:
