The Milne and the Numorov methods as independent approaches for solving the Schrödinger equation: Test case for the deuteron model for odd-odd N = Z nuclei

In this paper, we present the Numorov and the Milne methods as independent approaches, redundant and complementary methods for developing a 'scientific software' to solve the Schrödinger equation in a test case of the deuteron-core pair model-which is based on the single particle (deuteron) shell model. The deuteron-core pair model is based on the assumption that N = Z nuclei are composed of deuteron-like clusters and are considered an n-p (T = 0) pair (deuteron) correlation in an odd-odd N = Z.
