چکیده

In this paper, we construct a method with eight steps that belongs to the family of
Obrechkoff methods. Due to the explicit nature of the new method, not only does it
not require another method as predictor, but it can also be considered as a suitable
predictive technique to be used with implicit methods. Periodicity and error terms are
studied when applied to solve the radial Schrödinger equation, considering different
energy levels. We show its advantages in terms of accuracy, consistency, and
convergence in comparison with other methods of the same order appearing in the
literature.
