WebBohr radius. The Bohr radius ( a0) is a physical constant, approximately equal to the most probable distance between the nucleus and the electron in a hydrogen atom in its ground state. It is named after Niels Bohr, due to its role in the Bohr model of an atom. Its value is 5.291 772 109 03(80) × 10−11 m. WebFeb 23, 2015 · The characteristic length when solving for the energy levels of the hydrogenic atom is the Bohr radius: a 0 ≡ 4 π ϵ 0 ℏ 2 μ e 2. For positronium, we can calcuate the reduced mass, μ: μ = m 1 m 2 m 1 + m 2 = m e m e m e + m e = 1 2 m e. giving a reduced mass of about half that for hydrogen.
