Values of the net ionization coefficient lambda/sub 1/ in BF/sub 3/ have been determined from spatial current growth measurements in uniform electric fields E over the range 1.07 x 10/sup -15/< or =E/N< or =17.0 x 10/sup -15/ V cm/sup 2/ for gas densities N in the range 4.07 x 10/sup 16/ < or =N< or =348 x 10/sup 16/ cm/sup -3/. For the limited range 1.07 x 10/sup -15/< or =E/N< or =1.70 x 10/sup -15/ V cm/sup 2/, values of the ionization and effective attachment coefficients have also been determined. Within the limits of experimental uncertainty all the coefficients are found to be functions of E/N only. The limiting value of E/N at which lambda/subl/=0 is found to be 1.13 x 10/sup -15/ V cm/sup 2/. (AIP)
