Abstract : This final report describes briefly (a) a microwave system for measuring the electron density in decaying plasmas over t density range of about five thousand, (b) an experimental tube for measuring the value of the mobility of positive ions by means of the transit-time method, and (c) the results obtained during the period of the contract. The studies were confined to the rare gas ions and excellent agreement was found between the value of the mobility of atomic and molecular ions as determined from ambipolar diffusion coefficient measurements and those found by means of the ion transit-time method. The influence of the presence of negative ions on the ambipolar diffusion coefficient of electrons was demonstrated. The recombination coefficients of molecular neon and molecular argon ions were found to be independent of pressure and the values were in excellent agreement with previous studies. (Author)
