Through the measurement of the hfs of dilute alloys of gold with iron, cobalt, and nickel, the magnetic moment of the first excited state of Au/sup 197/ has been measured as +0.38 plus or minus 0.08 nm. It was found that the hfs coupling constant in the alloys is closely proportional to the magnetic moment of the ferromagnetic metal. The value of the effective hyperfine field for the iron alloy is H' = (1.46 plus or minus 0.16) x 10/sup 6/ gauss. A study of the isomer shift of the goldnickel ailoy system as it relates to ferromagnetism is presented. The recoilless absorption linewidth as a function of absorber thickness for metallic gold is given. The halflife of the first excited state of Au/sup 197/ is found to be T/sub 1/2/ = (1.93 plus or minus 0.2)x 10/sup -9/ sec. (auth)
