Abstract
We propose a new version of the multipoint Pade technique to solve Sch rodinger equations in their first-order Riccati form. Our compact prod uct representation of wavefunctions interpolates or 'matches' availabl e approximants at several points. The mechanism of 'matching' determin es the energies and eliminates spurious solutions. On V(x) = mu(2) x(2 ) + lambda x(2)/(1 + gx(2)), its efficiency is illustrated numerically .
