Atomic, Molecular, and Optical Science Gateway

The AMOS Gateway hosts state-of-the-art atomic, molecular, and optical science (AMOS) software suites and provides the community with an easy-to-use platform for calculations involving the static and dynamic properties of multi electron atoms and molecules.

Codes are available for computing spectra, lifetimes and transition rates between bound states, cross sections for electron scattering, photoionization and solutions of the time-dependent Schrödinger equation in the presence of strong and ultrafast electromagnetic fields. While use of the gateway is free, you must create an account.
