ABSTRACT
The purpose of this article is to show that a neutron can have excited states. The well known characteristic feature of the Bohr atom is that its electron shell can exist in a stable ground state or in various excited states. These states differ by integer numbers of de Broglie waves filled in their electronic orbits. Considering neutron to be an analog of the Bohn atom [1] differing in relativistic nature of its electron, a question arises on a possibility for neutron to have similar excited states. The calculations of the properties of these states show that two hyperons Λ0 and ∑0 which are usually considered as elementary particles, are excited states of neutron.
