Is There a High Energy Particle Population in the Quiet Solar Corona?

December 6, 2006

Author(s)

Yuri Ralchenko, Uri Feldman, G. A. Doschek

A study of spectra emitted by the quiet solar corona indicates that the majority of line intensities originating in low-lying levels are consistent with isothermal plasma of ~1.3 106 K. Nevertheless, a number of line intensities and in particular those

Selective Excitation of Metastable Atomic States by Femto- and Attosecond Laser Pulses

September 1, 2006

Author(s)

A D. Kondorskiy, L P. Presnyakov, Yuri Ralchenko

The possibility to achieve high selective excitation of low metastable states of hydrogen and helium atoms by using short laser pulses with reasonable parameters is demonstrated theoretically. Interactions of atoms with laser field are studied by solving

Large-Scale Calculation of Dielectronic Recombination Parameters for Mg-Like Fe

June 20, 2006

Author(s)

I Murakami, T Kato, D Kato, U I. Safronova, T E. Cowan, Yuri Ralchenko

Energy levels, radiative transition probabilities, and autoionization rates for $1s^22s^22p^63l'nl$ ($n$=3-12, $l \le n-1$) and $1s^22s^22p^64l'nl$ ($n$=4-7, $l \le n-1$) states in Mg-like iron (Fe$^14+}$) are calculated by the Hartree-Fock-Relativistic

Comparing Plasma Population Kinetics Codes: Review of the NLTE-3 Kinetics Workshop

June 1, 2006

Author(s)

C Bowen, R W. Lee, Yuri Ralchenko

Comparison of plasma population kinetics codes, which has become an important tool for their testing and verification, was the subject of the 3rd Non-LTE Code Comparison Workshop held at the National Institute of Standards and Technology in December 2003
