Atomic Ionization Potentials

Class providing atomic ionization potentials (in eV) for atoms of given atomic number in a specified ionization state (i.e. with a given number of remaining electrons). Ionization potentials set the energy threshold for photo-ionization and are used in computing photo-ionization rates from a given radiation field spectrum in IGM and CGM calculations.

Default implementation: atomicIonizationPotentialVerner

Methods

potential → double precision

Returns the ionization potential (in units of eV) for a given atom in a given ionization state.

• integer, intent(in ) :: atomicNumber, electronNumber

atomicIonizationPotentialVerner

Implements an atomic ionization potential class, which provides potentials for all ionization stages of all atoms from H to Zn using data taken from Dima Verner’s code.
