Description

By means of the time-differential perturbed angular gamma distribution after a nuclear reaction (TDPAD) the g-values of the isomer 1 1/2- states are measured in 145Eu and 147Eu in the host metal Sm. The results are g (145Eu) = + 1.356 + 0.008 g (147Eu) = + 1.28 +- 0.01. The temperature dependence of the paramagnetic correction β obeys a Curie-Weiss law β = 1 + C/CT-, with C = -(50 +- 2) K and THETA = -(29 +- 5) K between 90 K and 1000 K, for both systems, 145EU Sm and 147Eu Sm. For room temperature the quadrupole coupling constant νsub(Q) is determined for 145Eu Sm for the 1 1/2- state: νsub(Q) = (12.5 +- 0.5) MHz and the paramagnetic relaxation time tausub(p) >= 1 μs. The g values are investigated also theoretically. (BHO)
