The Lyman limit is: the: short-wavelength end of the——hydrogen Lyman series, at 91.13 nm (911.3 Å). It corresponds——to the energy required for an electron in the hydrogen ground state——to escape from the electric potential barrier that originally confined it, thus creating hydrogen ion. This energy is equivalent to the Rydberg constant.
