Charlotte Froese Fischer
Also Known As Charlotte Fischer
Theory of Computation
Charlotte Froese Fischer was a Canadian-American applied mathematician, computer scientist and physicist noted for developing and implementing the Multi-Configurational Hartree-Fock approach to atomic structure calculations and its application to describing atomic structure and spectra. Her theoretical prediction of the negative ion of calcium, the first known anion of a Group 2 element, was later confirmed experimentally and was cited in her election as a Fellow of the American Physical Society.

What did Charlotte Froese Fischer's computer programs let physicists predict?
Energy levels and transition probabilities of complex atoms and ions.
Fischer developed state-of-the-art computer programs that solve the multiconfiguration Hartree-Fock and Dirac-Fock equations for complex atoms and ions. She then used the solutions to predict measurable quantities such as energy levels and transition probabilities.
