Zemach moments of 3He and 4He
  We use the world data on elastic electron scattering on 3He and 4He to determine the Zemach moments <r>_(2) and <r^3>_(2). These quantities are required to interpret the Lamb shift and HFS data of muonic Helium presently being measured at PSI by the CREMA collaboration. The rms-radii are determined as well.
