Highly excited states of atomic potassium in an external electric field
The photoionization spectrum of potassium in an external electric field is examined. Detailed studies are made of the strengths, spacing, and polarization dependence of the quasi-bound Stark states lying above E = O. The results are interpreted as the first observation of electric field enhanced …

One-dimensional hydrogen atom
The photoionization spectrum of highly excited hydrogen atoms in the energy range between E = 0 and E = E$\sb{\rm c}$ ionization thresholds is examined in the presence of a strong dc electric field. Atomic hydrogen is excited from the ground state via a three-photon process to high-lying excited …

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. …

Photoionization of Se Ions for the Determination of Elemental Abundances in Astrophysical Nebulae
Absolute single photoionization cross section measurements are presented for Se+ ,Se2+, Se3+ and Se5+. These measurements were performed at undulator beamline 10.0.1 of the Advanced Light Source (ALS) at Lawrence Berkeley National Laboratory using the merged-beams technique. All ions except Se5+ …

Excitation Spectroscopy of Krypton Molecular Rydberg States
An excitation spectrum of the Kr(,2) ('3)(SIGMA)(,u)('+)(1(,u),O(,u)('-)) excimer has been obtained for 335 (LESSTHEQ) (lamda) (LESSTHEQ) 445 nm and 480 (LESSTHEQ) (lamda) (LESSTHEQ) 545 nm, and Rydberg series of krypton dimers have been observed. The most pronounced peaks in the spectrum have been …
