Spin-flip scattering of conduction electrons from impurities in molten sodium

[摘要] The effects of four new impurities (Bi, Pt, Pd, and Ag) on theconduction electron spin resonance signal of sodium metal has beenobserved. Due to solubility problems, previous attempts to see effectsfrom these impurities have been unsuccessful. By going into the moltenstate these problems were surmounted. The spin-flip scattering crosssection of these impurities was determined. The cross section forbismuth is of particular interest in that it serves as a test of the"resonance hypothesis" theory proposed by Ferrel and Prange. In additionto scattering cross sections, the equilibrium solubilities of bismuth andpalladium were determined as a function of temperature. These curves wereused to determine the entropy and enthalpy of solution for bismuth andpalladium in sodium.
