Abstract
High resolution two-photon spectroscopy was applied to investigate isotope shifts of Ssns S0 Rydberg states of natural strontium in the range 10 ≤ n ≤ 70. While the isotope shifts between the even isotopes 84, 86, and 88 showed no change, a dramatic increase of the shift with increasing principal quantum number was found for the odd isotope Sr-87.
