# A program to calculate the eigenfunctions of the random phase approximation for two electron systems

## Description

Title of program: RPA TWO ELECTRON EIGENFUNCTION Catalogue Id: AAJD_v1_0 Nature of problem Knowledge of the eigenfunctions and eigenvalues of the random phase approximation (RPA) or time-dependent Hartree-Fock (TDHF) theory is sufficient for calculations of one electron properties for closed shell systems correct to at least first order in correlation. The eigenfunctions of two electron systems satisfy a pair of second order eigenvalue differential equations coupled by an integral term. These eigenfunctions, characterized by a principal quantum number n and an angular momentum quantum ...
