Relativistic semiempirical-core-potential calculations in Ca, Sr, and Ba ions on Lagrange meshes
Livio Filippin, Sacha Schiffmann, Jérémy Dohet-Eraly +2
Relativistic atomic structure calculations are carried out in alkaline-earth-metal ions using a semiempirical-core-potential approach. The systems are partitioned into frozen-core…
Relativistic polarizabilities with the Lagrange-mesh method
Livio Filippin, Michel Godefroid, Daniel Baye
Relativistic dipolar to hexadecapolar polarizabilities of the ground state and some excited states of hydrogenic atoms are calculated by using numerically exact energies and wave f…
Relativistic two-photon decay rates with the Lagrange-mesh method
Livio Filippin, Michel Godefroid, Daniel Baye
Relativistic two-photon decay rates of the and states towards the ground state of hydrogenic atoms are calculated by using numerically exact energi…
Accurate solution of the Dirac equation on Lagrange meshes
Daniel Baye, Livio Filippin, Michel Godefroid
The Lagrange-mesh method is an approximate variational method taking the form of equations on a grid because of the use of a Gauss quadrature approximation. With a basis of Lagrang…
