Lithium Photoionization Cross-Section and Dynamic Polarizability Using Square Integrable Basis Sets and Correlated Wave Functions.

摘要

The photoionization cross-section and dynamic polarizability for lithium atom are calculated using a discrete basis set to represent both the bound and the continuum-states of the atom, to construct an approximation to the dynamic polarizability. From the imaginary part of the complex dynamic polarizability one extracts the photoionization cross-section and from its real part the dynamic polarizability. The results are in good agreement with the experiments and other more elaborate calculations. (Atomindex citation 19:047651)
