Nodal Boundary Condition Method for Atomic Wave Functions and Transition Probabilities

A method is presented for computing valence atomic wave functions and transition probabilities. This method, called here the "nodal boundary condition method," is a modified self-consistent-field approach which makes some use of experimental term values in order to eliminate the need for calculating wave functions for the core electrons. As an application, the method is used to compute eigenvalues, wave functions, and oscillator strengths for thirteen atoms and ions having two valence electrons.
