Abstract: | The magnetic hyperfine splitting frequenciesν M=¦gμ NBHF/h.¦ of the 11/2? isomeric states129m Xe (T1/2=8.9d) and131mXe (T1/2=11.8d) in Fe were measured with nuclear magnetic resonance on oriented nuclei at temperatures of 10–15 mK as 188.0(1) MHz and 209.8(1) MHz, respectively, the samples being prepared with the technique of recoil implantation after (α, x n) reactions. The magnetic moments of129m Xe and131m Xe are deduced to be (?)0.8914(6)μ N and (?)0.9943(6)μ N, respectively. The missing γ-anisotropies for allγ-transitions following the decay of 36.4d 127Xe indicateI=1/2 for the ground state spin of127Xe. |
