Based on the theory of deformed Lie algebra, we construct a nonlinear spectrum generating algebra for the first Pschl Teller potential by use of the Hamiltonian and the natural operators.

The measurements have produced large sets of reliable atomic data, including ionization and recombination cross sections for charge balance calculations, line lists, excitation cross sections, and dielectronic recombination rate for interpreting X-ray line formation as well.
