Abstract
The rotation of the angular correlation between theγ-group at about 820 keV and the 80 keV radiation in the decay of Tm168 has been observed in an external magnetic field of 20300 gauss.
The result:ω R·τ=0,485±0,051 yields for theg R -factor of the 80 keV state of Er168:g R =+0,25±0,03.
The evaluation includes a paramagnetic correction factor of:β=7,26, (B eff=β·B ext).
The angular correlation is slightly attenuated by internal fields. For a liquid source of Tm (NO3)3 solved in 3 n HNO3, a measurement of the differential angular correlation as a function of the delay time gave:λ 2=(5,8±2,9)·107sec−1, assumingA 2(t)=A 2(0)·e −λ 2·t.
The half life of the 80 keV state was found to be:T 1/2=(1,92±0,04)·10−9sec in agreement with earlier measurements.
