WebThe simplest definition of the ground state of an atom refers to: Ground State (of an atom): the lowest possible energy level of the atom in question. To define this more broadly, we can say that the ground state is the state in which atoms are found if they are not charged or excited by external sources. WebAll calculations for such a system are performed on a two-dimensional subspaceof the state space. If the ground state of a physical system is two-fold degenerate, any coupling …
