Nuclear Magnetic Resonance Experiment on Metal Cadmium

The Knight shift, the line width and shape, and the spin-lattice relaxation time of the resonance line in metal cadmium are measured employing a nuclear magnetic resonance technique. The resonance line is asymmetric indicating an anisotropy of the Knight shift. From the analysis of these line shapes, the asymmetry in p-character of the conduction electron is estimated. The shift perpendicular to the c-axis is 0.42 percent and the shift parallel to the c-axis is 0.46 percent. The isotropic shift is 0.43 percent. In appendix, skin effect in metallic foil is discussed.
