✦ Synopsis

A new integral equation method for the numerical solution of the radial Schrödinger equation in one dimension, developed by the authors (1997, J. Comput. Phys. 134, 134), is extended to systems of coupled Schrödinger equations with both positive and negative channel energies. The method, carried out in configuration space, is based on the conversion of differential equations into a system of integral equations together with the application of a spectral type Clenshaw-Curtis quadrature. An accompanying general multichannel FORTRAN code is available upon request.

Recently an interesting new class of PDE integrators, multisymplectic schemes, has been introduced for solving systems possessing a certain multisymplectic structure. Some of the characteristic features of the method are its local nature (independent of boundary conditions) and an equal treatment of

In the framework of nonrelativistic quantum mechanics in 3 dimensions, we propose a new way of calculating the energies of the 1l-states from the properties of the 1s-state. The method is based on the generalized Bertlmann Martin inequalities, corrected to obtain approximative relationships relating
