AbstractAbstract
[en] It is shown what perturbation is required to variate the normalizing constants of the chosen levels and to shift separate energy levels in the rectangular well for the finite-difference Schroedinger eq. Peculiarities are found of the discrete case in comparison with the equation of motion with the continuous coordinate. The ordinary potential parameters vn (diagonal) determine the shape of the lower boundary of the allowed zone, and the un on the neighbour diagonals determine the width of the zone. The different influence of vn and un on the shifts of the energy levels in the rectangular well is clarified. The v pushes in one direction the levels symmetrically posed according to the middle of the spectrum, and un pushes them in opposite directions. 8 refs.; 12 figs
