“…Accurately known atomic data, such as energy levels and radiative transition properties, are not only important for basic atomic physics, but also for applications to diagnostics of plasmas. The spectra of F-like ions, especially for medium Z ions, including the iron period elements, are often observed in both astrophysical(e.g., Feldman et al 1998Feldman et al , 2000Ko et al 2002;Curdt et al 2004;Landi & Phillips 2005;Doschek & Feldman 2010;Shestov et al 2014) and laboratory plasmas(e.g., Gu et al 2007aGu et al , 2007bOuart et al 2011;Safronova et al 2012;Beiersdorfer et al 2014). Using specific spectral lines, one can obtain the most fundamental properties of the plasma, such as ionization state, electron temperature, electron density, and elemental abundances.…”

We have performed extensive multiconfiguration Dirac-Hartree-Fock calculations and second-order many-body perturbation calculations for F-like ions with Z=24-30. Energy levels and transition rates for electric dipole (E1), electric-quadrupole (E2), electric-octupole (E3), magnetic dipole (M1), and magnetic-quadrupole (M2) transitions, as well as radiative lifetimes, are provided for the lowest 200 levels belonging to the s s p configurations of each ion. The results from the two sets of calculations are in excellent agreement. Extensive comparisons are also made with other theoretical results and observed data from the CHIANTI and NIST databases. The present energies and wavelengths are believed to be accurate enough to aid line identifications involving the n=3 and n=4 configurations, for which observations are largely missing. The calculated wavelengths and transition data will be useful in the modeling and diagnostics of astrophysical and fusion plasmas.

“…On all tested foils, we found only thermal and ion beam damages from the plasma, but no holes from solid fragments and liquid droplets that are typically generated by solid targets [3,15]. These results were a testimony for the lack of debris, which was a significant improvement compared to analogous experiments with thin flat laser targets where many holes appeared after the first laser shot [15].…”

Abstract. Many aspects of physical phenomena occurring when an intense laser pulse with sub-ps duration and an intensity of 10 18 -10 19 W/cm 2 heats an under-dense plasma in a supersonic cluster/gas jet were studied to determine the relative contribution of thermal and non-thermal processes to soft and hard x-ray emission from debris-free plasmas.Experiments were performed at the University of Nevada Reno (UNR) Leopard laser operated with a 15 J / 350 fs pulse and different pulse contrasts (10 7 or 10 5
