get_isoelectronic_sequence

fiasco.get_isoelectronic_sequence(element, hdf5_dbase_root=None)

List of ions in the isoelectronic sequence of element.

Ions in the same isoelectronic sequence, that is, ions that have the same number of bound electrons, \(Z - z\), often share common properties despite having different charge states and being from different elements. These so-called isoelectronic sequences are typically denoted by the element with an atomic number equal to the number of bound electrons, e.g. C II is in the boron isoelectronic sequence or equivalently may be said to be boron-like. Given the name of a sequence, as denoted by an element label, this function returns a list of all ions in that sequence.

Parameters:

• element (str, int) – Name of sequence. Can be either the full name (e.g. “hydrogren”), the atomic symbol (e.g. “H”) or the atomic number (e.g. 1)

• hdf5_dbase_root (path-like, optional) – If not specified, will default to that specified in fiasco.defaults.
