Nuclear magnetic moment of 106Rh.

Abstract

Nuclear orientation and nuclear magnetic resonance measurements have been performed for $^{106}\mathrm{Rh}$ oriented at low temperature in iron and nickel hosts. From the results of the temperature dependence measurements of nuclear orientation, the magnetic moment of $^{106}\mathrm{Rh}$ was deduced as \ensuremath{\Vert}\ensuremath{\mu}${(}^{106}$Rh,${1}^{+}$)\ensuremath{\Vert}=2.52(5)${\mathrm{\ensuremath{\mu}}}_{\mathit{N}}$, which is very different from the value of 3.07(9) ${\ensuremath{\mu}}_{N}$ reported previously. From the nuclear magnetic resonance on oriented nuclei measurements of $^{106}\mathit{Ni}$, the magnetic hyperfine splitting frequency \ensuremath{\Vert}g${\ensuremath{\mu}}_{N}$${B}_{\mathrm{HF}/\mathrm{h}\mathrm{\ensuremath{\Vert}}}$ was determined to be 441.5(7) MHz. Using the hyperfine field ${B}_{\mathrm{HF}}$ (RhNi) of -22.49(5) T, the precise value of the magnetic moment of $^{106}\mathrm{Rh}$ was deduced: \ensuremath{\Vert}\ensuremath{\mu}${(}^{106}$Rh,${1}^{+}$)\ensuremath{\Vert} =2.575(7) ${\ensuremath{\mu}}_{N}$. The electric quadrupole interaction has been measured using modulated adiabatic passage on oriented nuclei in a nickel single-crystal host. A broad distribution of the quadrupole splitting \ensuremath{\Delta}${\ensuremath{\nu}}_{Q}$ is found, extending from 0 to 300 kHz.
