英文摘要	We calculate the diamagnetic spectrum of lithium at highly excited states up to the positive energy range using the exact quantum defect theory approach. The concerned excitation is one-photon transition from the ground state 2s to the highly excited states np with pi and sigma polarizations respectively. Lithium has a small quantum defect value 0 : 05 for the np states, and its diamagnetic spectrum is very similar to that of hydrogen in the energy range approaching the ionization limit. However, a careful calculation shows that the spectrum has a significant discrepancy with that of hydrogen when the energy is lower than -70 cm(-1). The effect of the quantum defect is also discussed for the Stark spectrum. It is found that the sigma transition to the np states in an electric field has a similar behavior to that of hydrogen due to zero interaction with channel ns.
