Atomic helium transitions from its metastable 2s 1S state to high np 1P (n = 14 to 36) Rydberg states have been observed via opto-galvanic spectroscopy for the first time. The observed transition frequencies agree well with predictions of quantum defect theory indicating the states are not strongly perturbed internally or by their environment. The levels are slightly broadened by He collisions and stray electric fields.
