The use of Daubechies' compact support wavelets in quantum mechanical eigenvalue problems is investigated. It is shown that these orthogonal multiresolution functions provide an efficient basis for systems in which the potentials vary strongly in different regions.

β¦ Synopsis
A method is proposed which allows the scattering problem to reduce to the eigenvalue problem. Unlike the usual method when the scattering phase is extracted from the asymptotits of solution of the Cauchy problem at a given collision energy, in the proposed method the collision energy is obtained from the solution of the Sturm-Liouville problem at a given scattering phase. The continuous analog of the Newton method is used for the numerical realization of the proposed method.

The matrix form of the molecular orbital equations is that of a generalized eigenvalue eq~iation, when the basis functions are non-orthogonal. Five algorithms for the reduction of this equation to standardαΊ½igenvalue form are analysed and compared. The behaviour of the algorithms as the overlap matri
