Abstract: | Nuclear magnetic resonance on oriented nuclei has been detected for the first time via the destruction of the anisotropy of characteristic Lx-rays. The new method can be applied to isomeric states which decay only via highly converted transitions, for which the standard NMR-ON technique — detection of NMR via the anisotropy of -rays — is not applicable. The X-NMR-ON technique has been used to measure the magnetic hyperfine splitting of193mpt (I=1322+; E=149.8 keV; T1/2= 4.3 d) to be ¦ g
NBHF/h¦=111.3 (3) MHz. with the known hyperfine field of –1280(27) kG the magnetic moment of193mpt is deduced to be ¦¦=0.7417(14) N. This magnetic moment differs strongly from the known magnetic moments of the 13/2+ isomeric states in Hg and Pb and195mPt. |
