The isotope shift for the Zeeman [ital g][sub [ital J]]-factor ratio, including relativistic corrections of orders [alpha][sup 2], [alpha][sup 2][ital m]/[ital M], and [alpha][sup 3], is calculated to high precision using variational wave functions. The finite-mass corrections coming from the mass scaling and from the mass polarization term are treated exactly. The result is [ital g][sub [ital J]]([sup 3]He, 2 [sup 3]S[sub 1])/g[sub G]([sup 4]He, 2 [sup 3]S[sub 1])=1+2.708 439 694 74(76)[times]10[sup [minus]9]. Our calculation significantly improves the previous theoretical prediction of Barkley and Hegstrom [Phys. Rev. A 14, 1574 (1976)] for this isotope shift.
