Abstract

Nuclear orientation and NMR/ON of114mIn implanted into Fe at an energy of 80 keV and dose of 3–5×1014 cm−2 is reported. The zero applied field resonance frequencyv 0=203.65(6) MHz is combined with the recently determinedB hf(InFe) of 286.8(3) kG to yield μ(114mIn)=+4.658(14) nm. The nuclear spin-lattice relaxation time for114mIn in iron is measured to be 88(18) s at 18 mK and the applied field dependence of the NMR/ON resonance frequency gives the Knight shift for the system as −2.4(6)%. The absence of measurable nuclear orientation in similarly prepared114mInCo sources is discussed.
