Sumario:Conduction electron spin resonance (CESR) spectra are reported for colloidal alkali metal particles in frozen solutions of sodium and potassium in hexa. Electron spin-lattice relaxation rates are governed primarily by spin-orbit coupling during spin-phonon scattering of high velocity electrons, an resistivity. A novel method of isolating the spin-orbit contribution to spin relaxation at 1.3 K is described: there is no evidence for freezing in of Umklapp pro. © 1975.
