From a laser spectroscopic study of isotope shifts in the 1{ital s}2{ital s} {sup 1}{ital S},{sup 3}{ital S}{r arrow}1{ital snp} transitions in {sup 3}He and {sup 4}He and of the hyperfine structure in the 1{ital snp} Rydberg states of {sup 3}He we have derived highly accurate information on mass-polarization effects in the 1{ital s}2{ital s} {sup 1}{ital S} and {sup 3}{ital S} states. The experimental results, which are in good agreement with recent, high-precision variational calculations, confirm an isotope dependence of {l angle}{bold p}{sub 1}{center dot}{bold p}{sub 2}{r angle}.
