Abstract
Using the relativistic configuration interaction Hartree–Fock method the
Hamiltonian matrices of Ce I, J = 4±, and Pr I, J = 11/2±, are studied.
These matrices can be characterized as sparse, banded matrices, with a
leading diagonal. Diagonalization of the Hamiltonian results in a set of
energy eigenvalues and corresponding eigenvectors and the purpose of this
investigation will be to characterize the Hamiltonian matrices and coupling
matrices of Ce I and Pr I, for both ls and jj coupling representations, using
various statistical predictions of Random Matrix Theory.
