Abstract
The deflection of beams of helium microdroplets by crossed jets of xenon or carbon dioxide shows that droplets of less than some 104 atoms of 4He or 105 atoms of 3He retain less than half of the momentum flux impinging at about 400 m/s relative speed. Increasing the cluster size or lowering the relative speed raise the momentum transfer, except for a minimum at about 110 m/s occuring only with 4He-microdropletsKeywords
