Abstract (EDP Sciences, SpringerLink, SAO/NASA ADS)
The interaction of superluminal radiation with matter in atomic boundbound and boundfree transitions is investigated. We study transitions in the relativistic hydrogen atom effected by superluminal quanta. The superluminal radiation field is coupled by minimal substitution to the Dirac equation in a Coulomb potential. We quantize the interaction to obtain the transition matrix for induced and spontaneous superluminal radiation in hydrogenlike ions. The tachyonic photoelectric effect is scrutinized, the crosssections for ground state ionization by transversal and longitudinal tachyons are derived. We examine the relativistic regime, high electronic ejection energies, as well as the first order correction to the nonrelativistic crosssections. In the ultrarelativistic limit, both the longitudinal and transversal crosssections are peaked at small but noticeably different scattering angles. In the nonrelativistic limit, the longitudinal crosssection has two maxima, and its minimum is located at the transversal maximum. Ionization crosssections can thus be used to discriminate longitudinal radiation from transversal tachyons and photons.
