摘要：
We introduce a new small-angle (theta<20 mrad) scattering deflection method to determine the size distribution of large liquid helium clusters formed by condensation in a supersonic expansion. The size distributions can be well represented by a log-normal model with mean sizes varying between 3x10(3) and 10(4) atoms depending on the source conditions. This deflection method can also be employed to size-select helium clusters.
