Combining density based dynamical correlation with a reduced density matrix strong correlation description
Robert van Meer, Oleg Gritsenko, Jeng-Da Chai
A combined density and first-order reduced-density-matrix (1RDM) functional method is proposed for the calculation of potential energy curves (PECs) of molecular multibond dissocia…
Approximate density matrix functionals applied to hetero-atomic bond dissociation
Robert van Meer, Jeng-Da Chai
A two-orbital two-electron diatomic model resembling LiH is used to investigate the differences between the exact Löwdin-Shull and approximate Hartree-Fock-Bogoliubov and Baerends-…
Charged pion form factor between =0.60 and 2.45 GeV. I. Measurements of the cross section for the H() reaction
H. P. Blok, T. Horn, G. M. Huber +84
Cross sections for the reaction H() were measured in Hall C at Thomas Jefferson National Accelerator Facility (JLab) using the CEBAF high-intensity, continous ele…
Simultaneous X-ray and UV spectroscopy of the Seyfert 1 galaxy NGC 5548.II. Physical conditions in the X-ray absorber
K. C. Steenbrugge, J. S. Kaastra, D. M. Crenshaw +8
We present the results from a 500 ks Chandra observation of the Seyfert 1 galaxy NGC 5548. We detect broadened emission lines of O VII and C VI in the spectra, similar to those obs…
AD Leonis: Flares observed by XMM-Newton and Chandra
E. J. M. van den Besselaar, A. J. J. Raassen, R. Mewe +3
The M-dwarf AD Leonis has been observed with the Reflection Grating Spectrometers and the European Photon Imaging Camera aboard XMM-Newton and also with the Low Energy Transmission…
Soft X-ray Spectroscopy of NGC 1068 with XMM-Newton RGS and Chandra LETGS
A. Kinkhabwala, M. Sako, E. Behar +7
We present high-resolution soft-X-ray spectra of the prototypical Seyfert 2 galaxy, NGC 1068, taken with XMM-Newton RGS and Chandra LETGS. Its rich emission-line spectrum is domina…
