NIST: Atomic Spectra Database Lines Form

Typical values for strong lines are of the order of 10 8 for neutral atoms and rapidly increase for ions. The oscillator strength is a dimensionless quantity which for strong lines (both in atoms and in ions) is of the order of unity. The line strength is proportional to A ki or f ik. This parameter does not depend on the transition energy.
