;
The spin-exchange optical polarization method was used to determine the sign and the magnitude of the hyperfine interaction constant in the ground (3p)/ sup 3/ /sup 4/S/sub 3/2 state of atomic P/sup 31/. The measurements were made by monitoring the transmission of circularly polarized rubidium D/sub 1/ (5P/sub 1/2 yields 5S/sub 1/2,) resonance radiation through a flask containing rubidium, atomic phosphorus, and a buffer gas as a function of the frequency of an external radio-frequency field. The value for the hyperfine interaction constant of P/sup 31/ obtained by extrapolation to zero pressure in a helium buffer gas is A(P/sup 31/) = +(55 055 691 plus or minus 8) cps/sec. The pressure shifts in cycles/ sec/mm Hg of the phosphorus hyperfine interaction constant for helium and neon buffer gases are +3.61 plus or minus 0.23 and +6.73 plus or minus 0.15, respectively.
