Higher-order two-body Levinson's theorems are proved for the class of potentials V E L' n L2 in terms of the energy moments of the trace of the time-delay operator. If V is smooth, the correction terms appearing in these trace relations are Korteweg-de Vries-type invariants. These theorems are used

A new iterative method to compute the Green's function for continuum systems is presented. It is based on a Newton polynomial expansion of the corresponding propagator, followed by accurate half-Fourier transformation. The new technique is remarkably stable, accurate and can handle very large system
The Green's function analysis of substituted and perturbed molecules is applied to the study of the vibrations of dibromogermane. The isotopic rules for the perturbation GeHnBr2 -\* GeDzBr2 are formulated and solved to arrive at the mixing parameter for each species of this molecule. The potential e
