摘要：

For the first time in the literature, a new two-stages symmetric six-step algorithm is developed and analyzed. The new algorithm has: tenth algebraic order (which is the highest possible order), vanished phase-lag and its first, second, third and fourth derivatives. good stability properties i.e. an interval of periodicity, equal to , the approximation of the first stage of the algorithm is done on the point and no at the usual point . Comparison on local truncation error analysis, Comparison on stability analysis, Comparison on accuracy and computational effectiveness of the solution of the Schrodinger equation.
