The recombination coefficient and mean frequency of electron capture by oxygen molecules were studied at 0.05 to 0.2 mm Hg with charged particle concentrations of 10/sup 10/ to 5 x 10/sup 11/ cm/sup -3/. A 250-mm long, 5-mm diameter cylinder with a strong magnetic field along the axis was used in order to eliminate the effects of particle diffusion into the cylinder walls. The magnetic field intensity varied to 8000 gauss. The influence of charged particle diffusion on plasma decay was negligible in the above fields, and elemination of electrons resulted from volume processes (electron-ion recombination and electron capture by oxy gen). The coefficient electron volume elimination, BETA == (1/ n) (dn/dt), was determined by the electron concentration curves. The curves of BETA as a function of oxygen pressure and mean concentration was expressed by BETA = nu /sub cO/P plus or minus alpha n, where nu /sub cO/ = (9 plus or minus 1) x 10/sup -4/ mm Hg/sup -1/ sec/sup -1/, and alpha = (1.9 plus or minus 0.1) x 10/sup -7/ cm/sup 3/ sec/sup -1/.
