Neutronium or Neutron?

Abstract

In a previous article, we proposed a hypothetical state of the hydrogen atom  - Neutronium. In the typical hydrogen atom, the electron is assumed to orbit the proton, while in the Neutronium, the converse is assumed, i.e., the proton orbits the electron. In this paper, we argument that, under certain assumed conditions, a free Neutronium may be unstable while a non-free Neutronium is stable when confined.
