On the Swarm Method for Determining the Ratio of Electron Drift Velocity to Diffusion Coefficient

摘要: The use of data from swarm experiments for electron energies approaching those corresponding to thermal equilibrium demands results greater precision than has hitherto been available. In order examine the possibility producing such data, method detennining W / D extensively examined over a range values parameter E / p where agreement between recent investigations is not good. A number factors influencing accuracy measurements this type are discussed. hydrogen which presented considered be subject an error less 1 %.
