 Abstract    C o m p a ra tiv e S tu d y o f V a r ia tio n a l T e c h n iq u e s fo r S c h r ö d in g e r E q u a tio n s . P o in tw is e Q u a lity C r ite r ia Different variational schemes for solving the Schrödinger equation are tested for the model potential of Kratzer-Fues. Wavefunctions are analyzed in terms of their global (expectation values) and local properties which are expressed as functions of coordinates. The Rayleigh-Ritz variation almost uniformly produces the most accurate expectation values. However the point properties show qualitatively different behaviour for different regions of the coordinate space. To define the local quality, a set of criteria is proposed.
