Bohr Radius

Bohr Radius
Definition:A fundamental constant used as atomic unit of length a0 = 4π ε0 ħ^2/me e2, where ε0 are the permittivity of vacuum, ħ the Planck constant/2π, me the electron rest mass and e the elementary charge, respectively. Using this atomic unit of length, many equations in quantum chemistry get a simple form.
a0 = 0.52917720859(36) x 10-10 m
Units:m
Symbol:a0
Scope note:Present value: 2006 CODATA recommended values
Synonyms:
Translation: DEBohrscher Radius
FRRadius de Bohr
