From a laser spectroscopic study of isotope shifts in the 1s2s 1S,3S1snp transitions in He3 and He4 and of the hyperfine structure in the 1snp Rydberg states of He3 we have derived highly accurate information on mass-polarization effects in the 1s2s 1S and 3S states. The experimental results, which are in good agreement with recent, high-precision variational calculations, confirm an isotope dependence of ;p1;p2;.. AE © 1990 The American Physical Society.
