Positive energy Sturmian states for two-Coulomb-center problems
- Department of Physics and Astronomy, University of Tennessee, Knoxville, Tennessee 37996-1501 (United States)
Properties of two-center Coulomb Sturmian basis sets are discussed. Analytic and numerical techniques to calculate these functions and coupling matrix elements are developed. A class of Sturmian functions is found that has no analytic continuation to negative energies and is not present in one-center potentials. Advantages of Sturmian sets over conventional eigenstate sets are emphasized. {copyright} {ital 1997} {ital The American Physical Society}
