The time-differential directional-correlation function of the the half- life of the 1.094-MeV state in /sup 168/ is found to be 107.3 plus or minus 2.2 nsec. The time-differential behavior of A/sub 22/(t) shows a possible time- dependent interaction with a decay constant lambda /sub 2/ = (1.0 plus or minus 0.5) x 10/sup 7/ nsec/su p -1/. Extrapolation of A/sub 22/(t) to zero time- delay gives A/sub 22/(0) = 0.007 plus or minus 0.004, which is compatible with spin 4 for the 1.094-MeV state and multipolarity M1 + < 8% E2 for the 448-keV transition. The g factor of the 1.094-MeV state has been measured, by use of the consant-angle-differential-delay method, and is found to be g = + 0.45 plus or minus 0.02. The time-dependent perturbation is interpreted in terms of rapidly fluctuating 4f electron magnetic hyperfine fields with a time-averaged value of 0.9 MG in Er/sup 3/ at room temperature. (auth)
