Nuclear Magnetic Resonance of Indium Metal at 4.2°K

Abstract

The nuclear magnetic resonance spectrum of indium metal power has been measured at twelve magnetic-field points in the range of 17.0 to 30.5 kG at 4.2\ifmmode^\circ\else\textdegree\fi{}K. The analysis of this spectrum gives the isotropic Knight shift as +0.80\ifmmode\pm\else\textpm\fi{}0.02%, the anisotropic Knight shift as -0.05\ifmmode\pm\else\textpm\fi{}0.02%, and the nuclear quadrupole spliting parameter ${\ensuremath{\nu}}_{q}$ as 1.884\ifmmode\pm\else\textpm\fi{}0.002 Mc/sec. All three of these quantities were determined at each of the twelve field points, and no field dependence has been observed in this range.
