• Descrição: We obtain the exact energy spectrum of nonuniform mass particles for a collection of Hamiltonians in a three-dimensional approach to a quantum dot. By considering a set of generalized Schrödinger equations with different orderings between the particle’s momentum and mass, the energy-bound states are calculated analytically for hard boundary conditions. The present results are of interest in atomic physics and quantum dot theory. Graphic Abstract
