Ionization by electron impacts and ionization potential depression
Djamel Benredjem, Jean-Christophe Pain, Annette Calisti +1
We calculate the cross-section of ionization by free-electron impacts in high or moderate density plasmas. We show that the so-called ionization potential depression (IPD) strongly…
Plasma density effects on the electron impact ionization
Djamel Benredjem, Jean-Christophe Pain, Annette Calisti +1
We present new results on the ionization by electron impacts in a dense plasma. We are interested in the density effect known as the ionization potential depression and in its role…
Inequalities for exchange Slater integrals
Jean-Christophe Pain
The variations of exchange Slater integrals with respect to their order are not well known. While direct Slater integrals are positive and decreasing when the order incre…
Checking the reliability of opacity databases
Jean-Christophe Pain, Patricia Croset
Mathematical inequalities, combined with atomic-physics sum rules, enable one to derive lower and upper bounds for the Rosseland and/or Planck mean opacities. The resulting constra…
Schroedinger equation on a generic radial grid
Christopher Bowen, Jean-Christophe Pain
In this note, we discuss the choice of radial grid in the numerical resolution of the Schroedinger equation. We detail the transformation of the equation resulting from a change of…
