We present a simplified radiation hydrodynamic model based on the fluid dynamic equations and the radiative transfer equation, which can be used to investigate the radiation properties and dynamics evolution of highly charged ions in a laser-produced plasma in vacuum. The outputs of the model consist of the evolution of the electron temperature, atom, and(More)
Multiconfiguration Dirac-Fock (MCDF) method was employed to calculate the first five ionization potentials, electron affinities, resonance excitation energies, oscillator strengths, and radii for the element Uus and its homologue At. Main valence correlation effects were taken into account. The Breit interaction and QED effects were also estimated. The(More)
The hyperfine induced 2s2p P0, P2 → 2s 2 S0 E1 transition probabilities of Be-like ions were calculated using grasp2K based on multi-configuration Dirac-Fock method and HFST packages. It was found that the hyperfine quenching rates are strongly affected by the interference for low-Z Be-like ions, especially for 2s2p P0 → 2s2 S0 transition. In particular,(More)
Hyperfine induced 1s2s S0 → 1s 2 S0 M1 transition probabilities of He-like ions have been calculated from relativistic configuration interaction wavefunctions including the frequency independent Breit interaction and QED effects. Present results for Eu and Gd are in good agreement with previous calculations [Phys. Rev. A 63, 054105 (2001)]. Electronic data(More)
The magnetocrystalline anisotropy of a ferromagnet is determined by its crystal structure and is thus an inherent source of magnetic anisotropy.[1,2] It is the key to an understanding of ferromag-netism itself and is still actively investigated even for apparently well-understood materials such as Fe.[3-5] The magnetocrystalline anisotropy energy of bcc Fe(More)
Magnetic susceptibility χ of pristine and brominated arc-produced sample of multi-wall carbon nanotubes was measured from 4.2 to 400 K. An additional contribution ∆χ(T) to diamagnetic susceptibility χ(T) of carbon nanotubes was found at T < 50 K for both samples. It is shown that ∆χ(T) are dominated by quantum correction to χ for interaction electrons(More)
