In the present work, a nonrelativistic analytical model is presented and used to modify the Schrödinger equation for subatomic scales with two-dimensional new anharmonic sextic potential (2DNASP) for atomic nuclei in noncommutative two-dimensional real space-phase (NC: 2D-RSP). We applied the generalized Bopp’s shift method to obtain 2DNASP, which is composed of ordinary anharmonic sextic potential and new additive part proportional to the infinitesimal parameter ?. We have also observed the kinetic term containing a new additive part proportional to the infinitesimal parameter . Thus, the global potential proportional to two infinitesimal parameters allowed us to consider the perturbation terms due to (space-phase) noncommutativity. Furthermore, the standard perturbation theory allowed us to find the corrections and corresponding to spin-orbital interaction and modified Zeeman effect, respectively. These corrections allowed us to find global energy levels , which depend on the discrete atomic quantum numbers (j, l, s, m) and the parameters of the studied potential (a, b, c), and we constricted the corresponding Hamiltonian operator . We have also generalized our obtained results to include the other nuclei’s atoms with spin differs from . This study has allowed us to obtain the energy spectrum in the extended quantum mechanics, which interpreted three physical phenomena. The first one is an ordinary two-dimensional new anharmonic sextic potential, while the second and third are the automatic appearance of spin-orbit interaction and modified magnetic influence, these phenomena were generated from the property of noncommutativity of space and phase. The obtained analytical results (the energy eigenvalues and the corresponding Hamiltonian operator) are in good agreement with the existing results. The previous results, in ordinary quantum mechanics, become special cases when we make simultaneously the limits . |
