• Velocity distribution in potassiuun molecular beams is measured by time-of-flight (TOF) method using a surface-ionization detector, which has high sensitivity and signal-to-noise ratio. The residence time of potassium on tungsten filament surface has been confirmed before hand to be far less than TOF. To avoid troublesome computation for the dynamic response function of the electronic system a sampling method is employed, and the sampled tons are accumulated into a coulomb meter. Experimental intensity vs. time curves are compared with those by calculations. The calculations are carried out on the assumption of the Maxwellian velocity distributions in molecular beams with a gate function determined for the experimental system. As was the case in previous works, considerable deficiency of low velocity molecules is observed but general agreement with the theory is considered to be reasonable.
