The isotope shift for the 2{sup 3}{ital S}-2{sup 3}{ital P} transition between {sup 3}He and {sup 4}He has been measured with a laser-microwave spectroscopy technique to a precision of 1 ppm, or 30 kHz. Our result is 100 times more precise than previous measurements and is by far the most precise isotope-shift measurement ever made for a multielectron system. It provides, for the first time, not only a check for the specific mass shift, but also for the calculations of the nuclear volume shift, the relativistic corrections involving the coupling between electrons, and the QED contributions.
