In quantum mechanics, a particle in a spherically symmetric potential, is a quantum system with a potential that depends only on the distance between the particle and a defined center point. One example of a spherically symmetric potential is the electron within a hydrogen atom. The electron's potential only depends on its distance from the proton in the atom's nucleus. This potential can be derived from Coulomb's law.
