Nuclear-polarization energy shifts are calculated for the low-lying levels of muonic /sup 3/He and /sup 4/He. In /sup 4/He, the shift of the 2s/sub 1///sub 2/ level is found to be - 3.1 meV, in agreement with the result of Bernabeau and Jarlskog. The corresponding shift in /sup 3/He is - 4.9 meV. Other corrections to the energy levels are calculated, with the improved result that the total theoretical 2s/sub 1///sub 2/-2p/sub 3///sub 2/ energy difference in /sup 4/He is 1.8131 - 0.102r/sup 2/ +- 0.001 eV, where r is the nuclear rms charge radius (in femtometers). Together with the measured value 1.5274 +- 0.0009 eV, this implies r = 1.674 +- 0.004 fm, which is consistent with available electron scattering data. (AIP)
