Umbrella Inversion Energy Levels of AB_3 Like Molecules for J ≥ 0 Numerical Methods Versus Analytic Solutions

摘要

Some computational strategies are discussed to calculate the eigenvalues and the eigenvectors of the umbrella inversion problem for non zero angular momentum. Iterative and analytic methods are introduced with the purposes of their integration and of a rapid solution of the Schroedinger equation. Umbrella energy levels of the BH_3 molecule obtained with numerical and analytic procedure are also presented and compared.
