One-dimensional hydrogen atom

The photoionization spectrum of highly excited hydrogen atoms in the energy range between E = 0 and E = Ec ionization thresholds is examined in the presence of a strong de electric field. Atomic hydrogen is excited from the ground state via a three-photon process to high-lying excited states. Detailed experimental studies are made of the various properties of the resonant structures, and the results are compared to numerical calculations. It is found that the external electric field can be used to manipulate, control, and design specific atomic structures. These resonant structures are nearly onedimensional and whose electronic distributions are highly extended along the field, and which may have enormous electric dipole moments. Such one-dimensional hydrogen atoms are ideal tools for studying a number of physical phenomena and applications.U of I OnlyThesi
