Experimental Photoionization Cross-Section Measurements in the Ground and Metastable State Threshold Region of Se+
N. C. Sterling, D. A. Esteves, R. C. Bilodeau +4
Absolute photoionization cross-section measurements are reported for Se+ in the photon energy range 18.0-31.0 eV, which spans the ionization thresholds of the 4S_{3/2} ground state…
New Atomic Data for Trans-Iron Elements and Their Application to Abundance Determinations in Planetary Nebulae
N. C. Sterling, M. C. Witthoeft, D. A. Esteves +6
[Abridged] Investigations of neutron(n)-capture element nucleosynthesis and chemical evolution have largely been based on stellar spectroscopy. However, the recent detection of the…
Blackbody radiation shift, multipole polarizabilities, oscillator strengths, lifetimes, hyperfine constants, and excitation energies in Ca+
M. S. Safronova, U. I. Safronova
A systematic study of Ca+ atomic properties is carried out using high-precision relativistic all-order method where all single, double, and partial triple excitations of the Dirac-…
Colloquium: Physics of optical lattice clocks
Andrei Derevianko, Hidetoshi Katori
Recently invented and demonstrated, optical lattice clocks hold great promise for improving the precision of modern timekeeping. These clocks aim at the 10^-18 fractional accuracy,…
Generation of Ultrafast Jets through the Implosion of a Nested Conical Wire Array
Friedwardt Winterberg
It is shown that in contrast to the electric pulse power driven implosion of a single conical wire array, the implosion of a nested conical wire array with opposite alternate openi…
Discrete Data Assimilation in the Lorenz and 2D Navier--Stokes Equations
Kevin Hayden, Eric Olson, Edriss S. Titi
Consider a continuous dynamical system for which partial information about its current state is observed at a sequence of discrete times. Discrete data assimilation inserts these o…
