Parallel scalability of Hartree-Fock calculations.

Quantum chemistry is increasingly performed using large cluster computers consisting of multiple interconnected nodes. For a fixed molecular problem, the efficiency of a calculation usually decreases as more nodes are used, due to the cost of communication between the nodes. This paper empirically investigates the parallel scalability of Hartree-Fock calculations. The construction of the Fock m...

Multiconfiguration Dirac-Hartree-Fock calculations of transition rates and lifetimes of the eight lowest excited levels of radium

The multiconfiguration Dirac-Hartree-Fock (MCDHF) model has been employed to calculate the transition rates between the nine lowest levels of radium. The dominant rates were then used to evaluate the radiative lifetimes. The decay of the metastable 7s7p 3P0 state through 2-photon E1M1 and hyperfine induced channels is also studied.

Hartree-Fock-Roothaan calculations for many-electron atoms and ions in neutron-star magnetic fields

The quantitative analysis of the electromagnetic spectra of isolated neutron stars by means of model atmosphere calculations requires extensive data sets of atomic energy values and transition probabilities in intense magnetic fields. We present a new method for the fast computation of wave functions, energies, and oscillator strengths of medium-Z atoms and ions at neutron star magnetic field s...

Storage-ring measurement and multiconfiguration Dirac-Fock calculations

The electron-ion recombination rate coefficient for Si IV forming Si III was measured at the heavyion storage-ring TSR. The experimental electron-ion collision energy range of 0–186 eV encompassed the 2p nl n′l′ dielectronic recombination (DR) resonances associated with 3s→ nl core excitations, 2s 2p 3s nl n′l′ resonances associated with 2s → nl (n = 3, 4) core excitations, and 2p 3s nl n′l′ re...
